Summary: My husband got me a Nuvi 3790LMT GPS for Christmas - I was all excited and tried it out over the weekend & had questions, which I sort of expected because I have not used a GPS before. Oh well, that's what tech support is there for, right?
Summary: I bought this as a replacement for Nuvi 705 because the blue tooth function suddenly became dysfunctional on the 705. So far, I've learned to hate the thing. It's just frustration. The device behaves in erratic matter. Sometimes it wants to display all the street names.
Summary: The battery will not survive being unplugged at all. And it will not charge from the car charger. You have to charge it on a wall charger at home, and them immediately plug it into your cigarette lighter.
Software update does not work, Touch Screen difficult to use
27 March 2011
Summary: The touch screen does not always work. The "free" software update from Garmin failed 4 times. Once a route is selected, the "red-x" button to cancel the route is grayed out so the trip cannot be cancelled. It takes this unit about 5 minutes to find a satellite.
Summary: Do not buy this product if you own a Mac. The software used to update maps and send location data to the unit simply does not work on a Mac. Keep looking. Shame on Garmin for their lack of support!
Summary: Was working well with some exceptions (such as periodic blanking out that other users have also reported) until yesterday when the maps disappeared leaving just a grey screen. I tried turning it off and back on but it will not start up. Past the 1 year warranty so too bad for me.
Summary: I ordered the wrong part number and did not get the unit I wanted. When the GPS arrived I turned it on to try the voice program and found this was the wrong model. The same day I received this I asked to exchange but was told once I turn it on it's mine.
