In my opinion, the Legend C is the same as the GPSMAP60cs but with a smaller screen and less memory. You'll see that if you do a comparison on the Garmin web site.
I didn't realize that you can't plug an external antenna, but even the 60cs needs extra maps and if you want rechargable batteries, that's an option. I have US topo and 24K topo for it.
Now if your talking about vehicle navigation, I think all the Garmin handhelds fall short, that's why I use the c320 which comes with City Select.
-
I use the belt clip provided with my 60cs. I attach it to my waist strap on my backpack. It sits in front of me to the side which makes it very easy to clip and unclip as needed. I used it this way in Shenandoah NP last month and it always kept locks on satellites.
Now I wonder, do the higher end units (besides the x series) have better sensitivity?
-
Also, depending on the mapping, some units will ask you if you want to stay on the trail or take the road when being a pedestrian (hiker).
-
I think we are missing the point. A gpsr clock tells you what time it is no matter where in the world you are. Time zones aren't linear, but the almanac takes care of that, just like letting you know the sunset and sunrise, moonphase, etc. no matter where you are.
-
Is anyone building transparent topo overlays for City Select/Navigator for the entire US? Or is this a question of Zoom levels and Garmin's ability to autozoom?
-
So would we assume that the Garmin units use "true" mills vs US or Russian military?
-
Did you create the folder C:\Garmin\Topo\East? Did you transfer the content of your topo East CD to this folder?
Did you repeat this for each CD, ie C:\Garmin\Topo\West, etc.
Also, in the registry HKEY_LOCAL_MACHINE
Software
Garmin
Mapsource
Products
you need to modify the keys 6,7,8,9 for East, West, Hawaii, and Alaska respectively.
If your keys match the folders that you transferred your CD's to, it should work.
-
Can someone post this procedure like under FAQ or something else? I've also seen a posting on adding topo (contours) to City Select which is similar. This would save reposting everytime this or related question is asked.
Also, wouldn't it be great to keep the routing ability after recompiling?
Is this possible?
-
Yes, it is obvious that Garmin wants to push out new products without refining the issues of the existing products. They can't offer updated software without advertising Beta after Beta. They just don't have the willingness to expend the necessary resources for quality control. For example, the new x series.....how stupid is it to offer SD cards that don't hold waypoints, tracks, or routes.
The problem is that each time Garmin comes out with a new bell or whistel, there are plenty of GPSr junkies that will go out and buy them and then ten minutes later tell everybody how wonderfull they are.
As per above, there are Garmin marketing agents that are constantly dredging this site and others.

If I loaded City Navigator, 24K, US Topo, and Worldmap, and I was in the area covered by 24K, what would be the hierarchy?
If I loaded City Navigator, US Topo, Blue Chart, and Worldmap, and I was in the vicinity covered by all 4 maps, what would be the heirarchy?

Ask yourself what UTM is. O.K., you probably answered that is is merely a projection of Long/Lat. to a 2D system. Long./Lat is more accurate, but unlike longitude, latitude keeps getting squished closer and closer together as you go north or south from the equator. "But I need a coordinate system so I can calculate distances and create designs in an appropriate mathematical format, and plot things with a simple ruler.", you say. "What do I do?", you ask. You project to the best extent your round cap of your theoritical ellipsoid from Long./Lat. to a flat surface like your map, ie. UTM. Metric has nothing to do with accuracy, it is just what was decided in defining UTM coordinates.
"So how do I compensate for the squishing affect as I move north-south, and east-west?", you ask. The designation of UTM changes for to incorporate the corrections, ie. 15,16,17 R,S,T, etc. keeping UTM on a 2D grid.

In principle, the three-dimensional coordinates of a single physical point should therefore be the same in both the WGS84 and NAD83; in practice, small differences are sometimes found. (The discussion is technical so go here):
http://www.mentorsoftwareinc.com/resource/Nad83.htm
If your working with US maps, I think it would more likely then not using the UTM projection from the NAD83 system. However, from the article, it's nothing to worry about if using one or the other:
"If such a set of three-dimensional Cartesian coordinates is converted to latitude and longitude using the two coordinate systems, there would be no difference in the longitudes, and the latitude difference would be
~ f sin 2Ø/sin1"
which reaches a maximum value of 0.000003 second of arc (or 0.0001 meter) at a latitude of 45 degrees. It is assumed that most users will ignore this very small difference."

The most basic is the etrex.
It has a trackback feature to let you go back the way you came. No maps, but with the additional purchase of Trip and Waypoint Manger, you can keep a record of all of your Waypoints and tracks.
If you can plot the Long./Lat or UTM coordinates of USGS maps, before your outing you can chart all of the locations in or about your trek and download them to the unit, so you will always know how far you are from these points.
You can create your routes and know where you are in relation to your routes, and you can always use the backtrack feature to go back the way you came.
This would come to about $100

Yes, you will be "capturing" the image on screen and saving it as a bmp file.

Garmin c320 and GPSMAPCS

I just got a 60CSx yesterday and it truely is amazing. under 3 floors I can get 30 foot accuracy indoors!
That's pathetic! Do you really need to find your way around the house with a GPS?!

That's it! I'm not posting on this topic anymore.

As for the altimeter (barometer): The altimeter use of the barometric sensor is not really a great advantage, the gps altimeter is more than enough. Additionally, the barometric sensor is almost useless for weather observations, as it only records pressure when the gps is on. To make weather observations a longer recording time is needed. Ok, if you have had the gps on for several hours, you can estimate the weather by checking the pressure trend in the last 4-6 hours, but a longer time frame would be better. Theoretically plotting altitude profiles is possible as well with the normal gps altimeter (not the barometric), but garmin decided not to put this feature in the csx, well maybe a firmware update would help..
Saying that you can get altimeter readings with the cx vs csx is like asking a one legged man to run a race against a marathon runner.
GPS readings without the use of a barimter is like betting on the one legged man.
First,
The shape of the earth (geoid) does not exactly match the WGS84 theoreticaly elipsode. This causes most points in the USA to be about -125 ft below the GPS calculation. The built in barimter works with the GPS unit to establish a very good correction to give actual elevation. The barimter is constantly calculating the pressure variations to establish the correct elevation in conjunction with the GPS reading.
Second,
I agree that the compass falls short. Most people like to move or walk when using a compass. But like I said in my previous posts, if you can't get a true elevation vs. distance profile using DEM mapping, this makes the altitude capability good only for getting spot shots, not profiles.
Third,
I think the x series sucks, I'll pass on it and I'll wait till Garmin gets it right.

CONTRARY TO POPULAR BELIEF, THE X DOES NOT STORE TRACKS, WAYPOINTS, OR ROUTES ON THE MICRO CARD!!!!! So I find the addition of the card useless.
I don't think that that belief is very popular. I think just a few people might believe or expect to save tracks, waypoints and routes on the card. The fact that Garmin's specifications for the unit shows a definite number of routes, waypoints and tracks should lead one to the conclusion that it's not changeable depending on what size memory card is used...
The addition of the memory expansion is what MANY users have been waiting for.
My offer to take your useless 60CSx off your hands still stands.
Neo Geo:
My 60CS is yours as soon as Garmin comes out with a unit that allows the storage of waypoints, tracks, routes on the SD card, retaining all the good features that I like and corrects the profile and routing creation ability in the unit.
That's it! I'm not posting on this subject anymore!

First thing is to make sure to go to the Garmin website and get the latest Mapsource upgrade. Once you have that, you should be able to open the .gpx files that you get from the website here. I believe the latest Mapsource is version 6.9.1.
Rich;)
Where do you get gpx files from this website?
-
Do you mean the 60CS vs 60CSx?
In my opinion the x is not worth the $150 more you pay.
The 60CSX loses the alarm clock and the ability to constantly monitor barometric pressure with the unit off. The x gains a micro card that allows storage of additional maps.
CONTRARY TO POPULAR BELIEF, THE X DOES NOT STORE TRACKS, WAYPOINTS, OR ROUTES ON THE MICRO CARD!!!!! So I find the addition of the card useless.
You can load custom waypoints on the x series, but I find that redundant on the CS because you can do exactly the same thing with regular waypoints.
There are more bugs with the x, but that is because it is relatively new and will eventually get ironed out.
The x has more sensitivity so that you will get a fix quicker, and better retain a fix under cover; however, you do not get any increase in accuracy.
Battery life is the same, weight, etc.
I have the 60cs and it has plenty of sensitivity, hasn't lost a fix yet in the outdoors.
Also, there is a newer SIRF chipset that has less drain on batteries.
Just consider what you really want in a unit and what you will be doing with it. You don't really need a compass since the units will always tell you what direction the next feature or waypoint is, but the altimeter is nice for plotting elevation profiles.
The S (sensor) units, C (compass).
The 60csx uses the same architecture as the 60cs, so I would hold out until garmin comes out with a better unit.

I recently bought a Gilson from GPSGeek, and I must say it works Great,
Good price, fast, reasonable shipping.
Just be carefull and Know what type of connector you want, the Mcx comes in a straight and 90 degree
version, straight is Better on my 60 cs
Dave
Carefull, If you're using the Belt Clip, then the 180 deg. MCX connector won't fit, you need the 90 deg connector (60cs)
Also, I have the Gillson 28 db. gain antenna, but so far, I have no problems with reception without the ext. ant. for 2 of my Garmin units.
Also, the new 38-50 db gain ant. will hog even more power from your batteries in an already hoggish unit.
In the final analysis, I wouldn't buy the antenna again.

I wonder if Garmin will give me City Select for my 60cs since I have City Select for my c320? (Can't use the c320 version for my 60cs)

The first error reported by GSK is: "Error sending waypoints: [ERROR] CreateFile: Access is denied.". Could it have something to do with the Norton antivirus/firewall? I'm running Windows XP, Home Edition, Service Pack 2. I'm not using a Palm Pilot, so I presume the detail relating to HotSync manager is irrelevant? I don't believe there is an internal modem, the one I use is an external for my broadband connection. I believe that there is only one COM port (COM1 is apparently free) for me to use. Like I said, a friend of mine successfully loaded a number of geocaches onto my Etrex before! It must be something stupid that is being overlooked?
I'm running XP Pro, all critical updates installed. Make sure in your Main menu, Setup, Interface, the Seriel format that is selected is "Garmin". If you use USB, the communication is automatically set without the need to select the type of interface.

CAUTION! CAUTION!
Some people THINK the csx stores POIs on the SD card.
WRONG.
It may seem that way until you load the card in a reader and see that this is actually NOT the case.
