I cannot rate the performance of the Nuvi 760 very well, but I can tell you about Garmin's service.
First of all, documentation is terribly inadequate.
As part of the service, purchasers are entitled to a free map update. That is where the problem started. It takes forever to download the installer. After that, you must download the map file and unzip it. Then you need to transfer this enormous file into your Garmin device. According to the screen message, this could take up to two hours.
Time after time, my transfer failed at 54%. I wrote to tech support. Not much help. I called tech support. This process takes hours. I was transferred to a higher level tech support. Still, no progress. The last techie said to send the device back and get another. Fortunately made the exchange very easy and fast.
Now I had a fresh GPS device. Same problem. Tach support apparently only reads parts of the letter. They ignore important passages. Still not help. FINALLY, I recieved a response from a sympathetic tech support guy. He said that I should try the usb port on the back of machine, not the front. I had already done that days ago. He also said to check the USB chipset. If they did not say "Intel," they may not work with the Nuvi. I checked the chips and they did not mention Intel. I guess that is the problem. The techie wrote that I should try another computer.
Had someone told me this weeks ago, I would have saved a lot of time and money. Why does not tech support share this information?
I am using an HP Pavilion 1730n with AMD Athlon dual core with 2 gigs of ram. A fairly competent machine. So, I will send this Nuvi 760 back. Get more detail about
