All of my tests had the GPS sitting on the ground or on a bench. At the very most, I picked it up as in the last test, but that didn't move it more than a meter or so. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Response to some other comments: It is well documented that GPS's typically assume that they are restarted near where they where last used. The documentation of every GPS I have ever bought says that if you turn it off and then transport it a long distance before turning it on again, it will take much longer to get a fix. The N810 without the AGPS package seems not able to do even this simple trick. Though I've never seen any problem with slow movement, I have seen (esp. on the N810) that highway speeds can hinder an initial fix. Cheers!

One of the first things I did was (of course) plug it into my Linux home PC (Debian 5.0.4, kernel 2.6.26-2). The GPS display showed the Garmin logo and a picture of itself plugged into a computer, but Linux was indifferent. Looking at the kernel log, it appeared the GPS wasn't playing nice. I either saw nothing at all, or just over-current change on port. I noticed that if I plugged it into the USB hub built-in to my Dell LCD, the hub would apparently reset, as the kernel would re-detect my mouse and flash card reader. Reading your entire message, it seems possible that Window's didn't work without a driver update and neither were able to work until it had been plugged in for a while and recharged. It may be that it draws too much power when the batteries are low? Removing the batteries so that it wasn't charging, just powering the electronics, might have made it work right off under Linux. Updating the firmware purportedly requires installing some proprietary software from Garmin. The instructions at this address _might_ work for your Garmin. However, they are specific to the Colorado: http://garmincolorado.wikispaces.com/Versions#Colorado Software Versions-Updates using gcd files There are links there for some other Garmin GPS's and a lot of information that is likely useful for more than just the Colorado.

And even if it were the case, 4 minutes seems like kind of a long time to wait when my Garmin can do it in around 10-20 seconds. In my case, we were sometimes out in the woods not near any WiFi signal and typically had much better performance than 4 minutes. The AGPS package at least knows how to remember where it was last and use that to help get it started. I think that the use of last known point is good for something on the order of 100 miles.

You will not get me to claim or defend that the N810 GPS is as good at getting a fix as other GPSs. It is not. However, my experience was clearly better than yours and once it has a fix, it does seem to be just as good. However, you might double check that AGPS is installed and configured. There may have been some relevant setup. Since the device belongs to my fiancee, I didn't do the install/setup, but I think I recall there being a setup/config step/page. Cheers!
