Question about Garmin nuvi 765T GPS Receiver
I just received my 765 on Thursday. I was attempting to update to the 2010 maps on my Mac (10.4.11) and it got part of the way through the update, then said there was a problem with the update and it couldn't finish. I believe it had index code -4. I was pretty tired, so I decided to deal with it later. I attempted to un-mount my Garmin, but it kept saying it was in use, so I kept it plugged in. I didn't think much about it, and closed my laptop to go to bed. When I did, the Garmin said system unavailable. I reopened my laptop and it had the device removal error, even though usually when I close the laptop the devices stay connected. I unplugged it and plugged it back in and it no longer recognizes it. Garmin's site said to try a reset, so I did, but now I can't even get it to power on. Is there anything else I can do to get it to turn back on? Customer support is closed until Monday, and I have a big trip I'm going on on Tuesday, which is why I bought the GPS now. Thanks in advance for any help you can give.

SOURCE: 2009 map update not loading
Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

All Garmin users,
There is no easy solution for this except to return your unit to the nearest Garmin outlet. You need to have very special equipment called an E-Prom burner or writer which only Garmin have. With this equipment they re-programmed (restore) the operating system back on your specific Garmin unit and model.
The problem why anybody can't do it is because there is no way you can access your Garmin unit from a pc or mac if the operating system is lost or damage on your Garmin, for the simple reason your pc or mac can't reconize the device that is pluged in, because there are no communication platform between the two devices.
As simple as that, life with it or send your Garmin gps to an autherized professional Garmin dealer.

I have the same problem of the Nuvi 850 being recognized by webupdater. I downloaded 4.30 firmware update using this link http://www8.garmin.com/support/download_details.jsp?id=4043 plug the unit in and ran the update. It will ask you to disconnect once it is done. The unit will boot up after a few update progress bars. Plug it back in and launch webupdater.
Fellow 850 owner.

Take a look at this site, http://www.garmin.be/missing.html Download and unzip the software, plug your garmin in the USB and start the updater.exe program. It gets you started again. Later on you can use the Webupdater to get possible newer software..
It worked for me and my Zumo550
