  1. I am not trying to take anything away from your sale of the GPSr, BUT........................I purchased this same Garmin Street Pilot c550 earlier this year on Ebay for less than $120. The unit was Garmin factory refurbished, with a Garmin warranty, and had all the latest 2009 maps for the US and Canada preloaded into the unit!!!! This paticular c550 GPSr has been discontinued for some time now! And you can purchase a current Garmin Nuvi for just over $100 if you shop around!
  2. Hello, IMO the best place to find any Loran is on Ebay. I do see them listed there occasionaly. Click on the link below, and check the GPS & Chartplotters, and the Other Electronics & Navigation listings. http://motors.shop.ebay.ca/items/Electroni...286Q2ec0Q2em282
  3. OK, do you have any pictures? And how much $$?
  4. You are looking at 2 older mapping software programs on CD. I purchased these software programs for my trip from Southern California to Nova Scotia, Canada in the fall of 2002. They were never installed on my computer. I decided to use a Delorme Earthmate, with Delorme's mapping software for the trip instead. The first is Microsoft's Streets & Trips 2002, and the second is Rand McNally's StreetFinder & TripMaker 2002. You can have both programs for $20.00 standard ground shipping in US or Canada included! PayPal ONLY! These programs are not current, but still should be good for general reference. You could possibly find some free updates for these programs if you do an agressive search online. The Rand McNally CD's will be shipped WITHOUT the jewelled cases, and will be put in paper sleves for shipping in a padded envelope! If you want the jewelled cases, there will be an additional $5.00 charge for shipping! For more detailed info on these programs, check the links below: http://www.microsoft.com/presspass/press/2...etstripspr.mspx http://www.gtpcc.org/gtpcc/streetfinder.htm
  5. Do you have any pictures of the actual camera you are selling?
  6. OK.................I must be extreemly STUPID, but I am having a realy hard time understanding your rationale that I was supposed to know that these items were USED just because there were 2 mounts for one cradle??????? Now, IMO if you have been selling online as much as you say you have, you should be much better at quoting more accurate shipping charges for your transactions! I have only been doing it for 2 years, but I am fairly good at it, and it is like I stated before, if I charge way too much for shipping I automaticly refund the overpayment to MY buyers!!! That is just good business! So you say you have been selling on Ebay for 10 years with 100% positive feedback, let's see a link to your Ebay feedback profile, so we can all see what a great seller you are!!!
  7. MY SYNOPSIS................................ IMO, the items I purchased from this seller were not accurately depicted in the picture, and I was overcharged for shipping! This is 100% MY fault for "ASSUMING THE ITEMS WERE NEW IN THE PACKAGE" and not getting a confirmation on the condition of the items before I agreed to make my purchase from "THIS SELLER"! This is NOT my first online purchase from a private party, and it will not be my last! I will just do a better job of keeping the honest people honest in the future!!!! And I will make most (if not all) my online purchases through Ebay, where there is more accountability for my purchases through Ebay's policies & feedback system. I have been buying and selling on Ebay for 2 years now, and I have 100% positive feedback for my selling transactions! I ACCURATELY describe my items I am selling, I only charge actual shipping costs, and NO handling fees to my buyers. And the few times I have overestimated, and overcharged for shipping, I automaticly refunded the difference back to the buyer!!! http://feedback.ebay.ca/ws/eBayISAPI.dll?V...eedbackAsSeller Anyhow, we can all learn from my experience. It is like the old saying.........."BUYER BEWARE"...........if it sounds like too good of a deal, then it is probably not as it seems!!!!
  9. I forgot to mention one other thing!!!! Before I commited myself to purchase this from the seller, I requested a quote for shipping to my postal code, he quoted me $14 for shipping. I then sent a counter offer to the seller for $35 shipping included!!! Seller agreed to my offer, and I paid for the items via PayPal. When I received the package today, the shipping label stated that shipping was ONLY $3.81
  10. I purchased these mounts from this seller, and I received them today. I assumed, that these items were new in the package from the picture that was posted. BUT, they were used, and put back into the original package for the picture. The items are in good used condition, but I failed to confirm with the seller as to if they were new or used. The moral of my story.............................NEVER ASSUME ANYTHING, always get a "confirmation" on the condition of items you purchase from someone on the web!!!!!!!
  11. I had this same problem to. Uninstalled both programs, reinstalled Mapsource.................works great now!
  12. If anyone from this web-site buys this GPSr through Ebay, I will include for FREE, a NEW IN THE PACKAGE - Garmin's Trip & Waypoint Manager CD. This CD retails for $30.00. You must let me know you saw this ad to receive the FREE CD with your purchase. https://buy.garmin.com/shop/shop.do?pID=664&pvID=1951
  13. Well................I should have given a bit more of an explination of what my intended usage is for this camera. Here in Nova Scotia we have been required (by legislation) as ATV users to build and maintain an ATV trail system through a network of ATV Clubs. We need to document areas/trails that need to be repaired & maintained, then submit a proposal to get funding for building new, and maintaining existing trails. I thought this cool camera would be good for "visual documentation" of specific areas to be repaired, enhanced, and/or the construction of new trails. Also, here is a better link for more technical info on this camera/GPS: http://www.duratechusa.com/Products/500SE.html
  14. Does anyone have any first hand info, or hands on experience with this camera? I am interested in using this for mapping ATV trails here in Nova Scotia. http://www.ricoh-usa.com/solutions/common/camera/default.asp
  15. For those who are interested, I have re-listed this item on Ebay, CLICK HERE to bid on this item.
  16. This item is now listed on Ebay.................CLICK HERE to bid on this item. Make sure you check my other auctions while you are there, or CLICK HERE.
  17. I tried to edit my original post to ad this updated pic, but the time for editing the post had expired! Here is an updated pic showing the Garmin PC cable that is included with this GPSr.
  18. 4 Sale - a lightly used GARMIN GPSV. I am the original owner of this item, and it is in like new condition. You get everything you see in the picture - the GPS receiver, HIGH GAIN remote antenna with a magnetic base, PC cable, vehicle dash mount, (Bicycle, ATV, Motorcycle) handlebar mount, quicks start guide, and owners manual. In the pic there is a 12v power cable instead of the OE Garmin PC serial cable. This item comes with the PC cable, and NO 12v cable. Everything else is included! For more detailed info & specs on this unit check Garmins web-site: https://buy.garmin.com/shop/shop.do?pID=155 I will also include for FREE, 4 new Alkaline Batteries! $125.00 Shipping to Canada, and the continental US included! PayPal ONLY. Email me at: randallholman@hotmail.com I am an Ebay & Paypal Verified seller, so you can buy with confidence! Check My Ebay Feedback Here!
  19. Look what I found.......................My first benchmark! I was out ATVing with some friends friday afternoon, and they said they were going to take me to a hilltop with a spectacular view. Well, we arrived at the spot, I dismounted my ATV, and I looked down and saw this marker: CLICK ON THE IMAGE FOR A LARGER PIC The UTM coordinates for this marker are: 20T - 535191 - 4988253 It is located near Sheet Harbour, Nova Scotia, on a hill overlooking Mulgrave Lake. Also, here is a pic of the view from this spot; CLICK ON THE IMAGE FOR A LARGER PIC
  20. To the best of MY knowledge..............................Magellans Topo software requires you to register it with a single GPSr. What is required for registration? That I don't know! I do know when you register street mapping software using a Garmin GPSr, they require a unit ID#, that is different from the units serial #. Hope this helps............?
  21. May 29, 2007 GPS World GPS technology giant Garmin is opening its technology to third-party developers. Today the company took the wraps off the Garmin Developer Web site for software developers and content providers who want to make their Web sites, applications and data content compatible with Garmin navigation systems. The Garmin Developer site provides both free and licensed Garmin resources and a library of application programming interfaces (APIs), toolkits and Web services offering six core products: Garmin Communicator Plugin, MotionBasedWeb Services, Content Toolkit, Garmin PeerPoint Messaging System, Garmin LBS Toolkit and Fleet Management Interface. "Until recently, third-party Web sites have been unable to communicate easily with Garmin devices," stated Charles Morse, Garmin's director of mobile and PND marketing. "We are making it easier for third-party content providers to leverage the huge community of Garmin devices by providing tools that will allow them to communicate directly with Garmin systems. This will create new markets for the programmers' content and services, while generating a grassroots movement that will spread Garmin's name and technology to consumers through third-party Web sites and content distribution channels." The Garmin Communicator Plugin API is a browser plugin and JavaScript support code that allows developers to transfer location data such as waypoints, track logs, maps and points of interest (POI) to and from a Web site and Garmin device. This will simplify loading location data to a Garmin GPS unit, according to the company. For example, on MotionBased.com, customers can quickly upload their activities in the form of track logs from their GPS devices. The cross-browser, and soon the cross-platform plugin, provide a consistent experience for MotionBased customers. Geocaching.com also integrates the plugin so that users can easily transfer selected geocache coordinates to their Garmin devices by clicking a new Garmin icon on the Geocaching.com site. Also available in Garmin Developer is the Content Toolkit, which lets developers compile secure POIs for Garmin GPS devices. Developers can then market this content to customers of Garmin products, creating an entirely new system of content, devices and customers, Garmin says. It expects future versions of the Content Toolkit to include routes and travel guide information. With the PeerPoint Messaging System, developers can utilize Garmin's location message format and send precise latitude and longitude information to phones running the Garmin Mobile XT application. Garmin anticipates that this published SMS interface will be sought after by location-based Web sites, fleet management systems, sales management applications and other applications that need to integrate remote destination sending and navigation. The individual who receives the location message will be able to save, view or route directly to the specified location with Garmin's turn-by-turn directions. Developers can also use the Garmin Location-Based Services (LBS) Toolkit to add location-based services to any Java-based mobile phone application. The LBS Toolkit incorporates Garmin navigation API, local search, real-time content delivery services and mobile advertising delivery services into one platform. This service was originally launched in late-2006 and several third parties have already taken advantage of the capability. Also available for smartphones, Garmin Mobile Smartphone provides mobile applications running on Windows Mobile or Palm OS devices with access to GPS information, interactive maps and intelligent routing including live traffic conditions. With these tools, developers can easily create LBS solutions for a wide range of Palm OS and Windows Mobile devices that are often already in use by enterprise customers, according to Garmin. The Garmin Fleet Management Interface enables fleet tracking, messaging, dispatch and navigation directly on Garmin's portable navigation devices, such as the StreetPilot, Nuvi and Zumo series. Utilizing third-party sensor and communication devices, companies can track GPS-based information like vehicle location, speed and direction of travel, distance traveled, and elapsed time, as well as fuel status, idle times, number of stops, cargo door access, cargo temperature, and battery and thermostat levels. The Fleet Management Interface also enables direct-to-driver communication via text messaging, as well as instant re-routing with new-destination message prompts, the company says. Garmin is also announcing the MotionBased Web Services API, which gives developers access to the same GPS content that MotionBased.com customers enjoy. This new service will enable third-party Web sites to store, manipulate and display Garmin GPS data with little or no development. The API will be available for testing in the summer of 2007 and will complement the Communicator Plugin API.
  22. What is the relationship between the NAD83 and WGS84 coordinates? One of the questions most frequently asked by GPS users is: How do I transform coordinates between the frames defined by NAD83 and WGS84? In effect, the GPS-user is trying to convert the positional coordinates that the receiver outputs or the manufacture proprietary software gives from one particular frame into the other. First of all, one should understand that the 3-D Cartesian frames to which the coordinates of the NAD83 and WGS84 refer are not identical. Their origin, axes orientation in space, and the unit of scale differ. Why? Simply, because the definitions of these two frames are based on different sets of observations, processing algorithms, and perhaps, geodetic assumptions. In practice, any terrestrial frame is defined by a set of points with assigned coordinates and velocities. These parameters materialize the reference frame in question. The velocities are important to change positional coordinates from one epoch to another. Thus, it is critical to understand that if we refine the coordinates and/or the velocities of the defining points by introducing new and more accurate observations, then, the origin, orientation and scale of the frame may change, but to a small degree. That is why sequence of reference frames has been developed. The latest version of NAD83 and WGS84 frames are specifically named NAD83 (CORS96) and WGS84 (G1150). Thus, when the receiver tells us that the computed coordinates using GPS observations are referred to the WGS84, they actually mean WGS84(G1150). On the other hand, if we use CORS coordinates data, or the OPUS service, the NAD83 reference frame to which these coordinates refer is actually NAD83 (CORS96). Consequently, rigorously speaking, a transformation between NAD83 and WGS84 should be interpreted as a transformation between NAD83 (CORS96) and WGS84 (G1150). Transformations between older realizations of NAD83 and WGS84 are now outdated and will not be discussed here. The question is then reduced to: How do we transform between NAD83 (CORS96) and WGS84 (G1150)? In absolute positioning, the frame WGS84 (G1150) is materialized not by the coordinates of marks on the surface of the Earth - as the NAD83 (CORS96) is - but by the coordinates of points in space, namely, the 3-D location of the GPS satellites (given by their precise or broadcast satellite ephemerides). Recent investigations [True, 2004] have shown that for all practical purpose, the WGS84 (G1150) frame is identical to the International Terrestrial Reference Frame of year 2000 (ITRF2000). Thus, except for very accurate geophysical calculations (crustal dynamics; tectonic strain determination, etc.), the WGS84 (G1150) is supposed to be aligned with the ITRF2000. In another words, both have the same origin, orientation, and scale. Once the WGS84 (G1150) and ITRF2000 are assumed equivalent [ ≡ is the mathematical symbol for equivalent], the question can be taken one step further and finally be formulated as: How do we transform between NAD83 (CORS96) and ITRF2000? In order to do this transformation, the epoch at which the coordinates defining the frames were determined must be known. The National Geodetic Survey (NGS) provides coordinates and velocities of all CORS stations on these two frames: ITRF2000, epoch 1997.0, and NAD83 (CORS96), epoch 2002.0, for the conterminous states. The epoch 2003.0 was selected for the state of Alaska due to the displacements originated by the Denali earthquake on November 2, 2002. The value of these coordinates and velocities as well as a description of previous ITRF frames can be consulted in the following CORS Web page: http://www.ngs.noaa.gov/CORS/metadata1/. Let’s assume now that we want to transform coordinates between the WGS84 (G1150) ≡ ITRF2000 and NAD83 (CORS96). The first thing that we need to keep in mind is that, in theory, the WGS84 (G1150) or ITRF2000 coordinates are the first one computed by the receiver software. However, they are originally obtained at the time of the observation, that is, the epoch corresponding to the mid-point of the observation window during the GPS data were collected. Consequently, we cannot compare coordinates from a set of observations taken today to results we determined one year ago. These two sets of coordinates must be reduced to a common epoch before the comparison is made. Let’s assume that we want to compare the coordinates we obtained today referred to the ITRF2000 to the ones at epoch 1997.0. Some receivers may be already doing this transformation from epoch to epoch and the final result may be already expressed in the frame WGS84 (G1150) ≡ ITRF2000 at epoch 1997.0. This will simplify the work involved, otherwise we should know the velocity of the GPS station due to the rotation of the tectonic plate on which is located. These velocities are not rigorously known until we have constantly monitored the point for a number of years. This is not generally the case and we must rely on geophysical models. The most common model used these days for correcting for plate rotations is called NNR-NUVEL-1A. This model provides the parameters required to correct for plate motion for all major plates (macroplates) forming the crust of the earth. Assume for an instant, that the velocities of the three components vx, vy, and vz, are known in cm/year for a particular point, then, the transformation between epochs could be simply written: x (epoch 1997.0) = x (epoch today) + vx * ( 1997.0 - epoch today) with similar equations for y and z. Once we have all observed points referred to a common frame and epoch, e.g. ITRF2000, epoch 1997.0, we will be able to compare apples to apples. Remember that this change from epoch to epoch may be already included in the software that you are using. In any case, one should know that all coordinates must refer to a common epoch. Finally, we are ready to transform between WGS84 (G1150) ≡ ITRF2000 at epoch 1997.0 and NAD83 (CORS96) at epoch 2002.0. In order to do this final step, the 14 transformation parameters (three shifts, three rotations, one scale and their variations with time) between the two frames are needed. The rigorous transformation is somewhat involved [soler and Snay, 2004], thus, the easiest approach is to use the software developed at NGS which is interactively available through the Internet. Its name is Horizontal Time Dependant Positioning (HTDP) and can be located at the following URL: http://www.ngs.noaa.gov/TOOLS/Htdp/Htdp.shtml. In fact, HTDP [snay, 1999] has also the capability of transforming coordinates from epoch to epoch using in the process model NNR-NUVEL-1A mentioned above. This software also could provide transformations from the WGS84 (G1150), assumed identical to ITRF2000, to NAD83 (CORS96). The text included on the HTDP Web page is self explanatory and sufficiently detailed for doing all types of transformations necessary when performing GPS work. Final comment. Although on November 5, 2006, the GPS satellite orbits provided by the International GNSS Service switch to frame ITRF2005, everything mentioned above is still valid. Nothing practically will change considering that the differences between ITRF2000 and ITRF2005 are smaller than the differences between WGS84 (G1150) and ITRF2000. Except for accurate geodetic investigations these differences could be assumed negligible. -------------------------------------------------------------------------------- References 1. Snay, R.A.

  23. YES, there is! For the past year I have been using a Garmin GPSV on my ATV in the deep woods here in Nova Scotia. I had to hook-up an external antenna to get better reception under the heavy tree cover. I just purchased a Garmin GPSMap 276c, and I don't need the external antenna on this unit. It seems to have a faster processor, and will pick up sattelites even indoors. So, IMO a newer unit should provide better reception, and coverage. Also, I have heard the units with the SirF chip seem to have a more sensitivity, and better reception?
  24. I was watching CSI on SpikeTV last night, and saw a commercial for the Garmin Nuvi. I thought this was kinda-cool since I have been using Garmin products for over 10 years now! Then I remembered all of the hype over their entry into TV advertising with their Super Bowl AD! So I got to thinking..............................I wonder what Garmin has done in the way of the stock market? I found that their stock has increased dramaticaly over a 3 year period. It has gone from $17.36 in May of 04 to $58.34 in May of 07. Anyhow, I just thought this was kinda interesting...............
