  1. Software version 2.80 from http://www8.garmin.com/support/download_details.jsp?id=1417 fixes this problem.

  3. I have checked and it fixes that bug where if you selected a geocache and went in to compass mode it would get stuck I have just realized this is a duplicate discussion (thats jet lag for yah!). I am closing this discussion and linking to the other discussion here .
  4. Details here: http://www8.garmin.com/support/download_details.jsp?id=1417 (Despite the change history stating that this update removes lithium ion as a battery choice, its still available on my Venture Cx !) (Also, I noticed this update isn't listed on the product page https://buy.garmin.com/shop/shop.do?cID=145&pID=410 ,under the updates & download link. I got it using the webupdater program)
  5. I agree. Also, the ' fraction of the Earth' thats covered by WAAS/EGNOS covers about 700 million people, possibly more (Europe & US). And I would imagine that's where quite a chunk of the worlds geochachers reside. If you live in Europe switch it on too.

  7. I use a program called img2gps. Its a small program, easy to use and free. Try it.
  8. There's an interesting in depth article on GPSr accuracy here.
  9. If you can, try get a price for the etrex Venture Cx. It is identical to the Legend Cx except you don't get the USB cable or the microSD card that comes with the LegendCx. But you can buy those items far cheaper as separate items later.
  10. Buy in the US if you can. The dollar rate is excellent plus products tend to be cheaper there for some reason. I got my Venture Cx there (with US base map and I am in Ireland) You can get a free official Garmin world wide base map here.( Scroll down to Garmin basemap section). I have installed it on my unit and it works great. Also if you need a microSD card get it in the US too. They're so cheap there, they're practically giving them away!
  11. I use GpicSync. Its free, GNU open source, very easy to use, and quite a small program. Perfect.
  12. Does the little "D" appear on the bars of the satellite page? If the D's arent there then even though WAAS is enabled the WAAS correction data hasn't been applied/received. On my Venture CX with WAAS enabled (and with the Ds displayed), my unit regularly displays an accuracy of +-1meter (3feet)
  13. Just to clarify, once the GPSr is locked on to the satellites the display clock is dead accurate.Its perfect. The issue I wanted to highlight was that from the time the GPSr goes 'offline' the accuracy is worse than a 'cheap and nasty' quartz watch. Surprising, really, considering how inexpensive, ubiquitous and yet very accurate quartz movements are. I know the Venture Cx is a relatively inexpensive GPSr but when you look at what it does it is really quite an astonishing little modern 'miracle' -all GPSrs are. From my layman's view synchronizing with 12 satellites, piloting a fix etc. are the difficult bits that the GPSr does, I would have thought keeping accurate time would have been easy! It came to mind that just as a desktop or laptop's clock is also inaccurate (if not let synchronize through the internet) maybe the GPSr also uses a similar type of timing system (as opposed to a quartz based clock)? May be that's got something to do with it. I agree to a point. As long as the unit is locked on to the satellites, I believe you have as near as you can get to a hand held atomic clock.However, I don't believe this is due to the accuracy of the internal GPSr clock, I think it is more to do with the fact it is 'networked' to the satellite's atomic clock, and is constantly being updated to the satelites clock. Once the GPSr is not allowed to synchronize with satellites for any length the GPSr's clock (relatively) quickly goes wrong.
  14. I noticed that when my VentureCx had not been used for a few days and I switched it on (indoors so it doesn't get a chance to 'synchronize' with any satellites) the time was wrong by 'tens' of seconds. So I did a test and I found that the GPSr was fast by 5 sec a day. I was a bit disappointed with that, as a cheap quartz watch would have much better accuracy than that. It was as I was trying to synchronize my digital camera and my GPSr clocks so that I could get very precise geotagged photos that I noticed this 'quirk'. After I had gone outside and the GPSr clock had 'synchronized' with the satellites I realized my digital cameras clock was now well out of sync with the GPSr. I am presuming (hoping!) that my GPSr isn't broken. I wonder, did anyone else notice this clock inaccuracy? Once the GPSr gets a fix on the satellites the clock does get corrected automatically.
  15. Well its good to know that they know.Hopefully Garmin will get their act together and release an update soon.
  16. What makes you say that Garmin are aware of the problem?
  17. I have to agree. The manuals are dreadful. I can perhaps understand Garmin not wanting to ship a large detailed manual with each unit (to save costs). But they should at least provide a decent online PDF manual.
  18. I am not really sure what the "upside down method" means. This may be of interest: http://forums.Groundspeak.com/GC/index.php?showtopic=162928

  20. I got a VentureCx a few weeks ago and upgraded to 2.70 without using it with 2.60 first. I have to say so far with regard to geocaching I have found it very good. Brings me to within 2-3 meters each time. Here is a little test I did trying to gauge the accuracy of my receiver. It basically tests the receiver against itself. There is a fixed wooden post in a field near by with a great view of the sky. I set the unit on the post and let it average a waypoint for 30mins or more each day over a week or so. What I noticed was the results varied a bit more than I thought they would have. For example (the worst deviation of one waypoint from another) one waypoint had an Estimated Accuracy (EA) of 0.7meters and another had an EA of 0.3 meters. Now if you double each EA and add the result you get 0.7x2=1.4 0.3x2=0.6 1.4+0.6= 2 meters So the combined maximum margin of error for the EA of the two waypoints should have been in or around 2 meters. So if the EA was correct the two waypoints should have been within 2 meters of each other. Yet the two waypoints are set 11 meters apart on the GPSr screen map ! I'm not sure what those results mean. Perhaps it shows varying atmospheric conditions can add quite a bit of error to a receiver's measurements. An interesting thing is there was minimal error north/south. The waypoints mainly differed east/west.
  21. Here is some info on USB power: http://en.wikipedia.org/wiki/USB#Power For anyone who is interested these are some photos of a Garmin USB car power adaptor which came with a Nuvi 270 sat nav. The specific power details are on the label. I dont know why the images will not show. You can see them here: http://commons.wikimedia.org/wiki/Image:Crgr03.jpg http://commons.wikimedia.org/wiki/Image:Crgr02.jpg http://commons.wikimedia.org/wiki/Image:Crgr01.jpg Maybe this: Doh!!! a little big. How do I resize the image?

  23. Very interesting. Well worth checking out. You put it perfectly when you say "Sort of ugly, but cool at the same time" (Sorry about the double post!)
