Summary: Like all gps, you can trust it, and you can not trust it. We've been over 30,000 miles across the US, and most of the time it is a wonderful lifesaver. BUT!!! you have to do your homework, and have a map, and use Google earth to zoom down on the road and make sure it is a road. You also need to check that state's DOT regarding the road condition; some roads are NOT maintained, like the road out of town going west from Albuqurque (sp?).
Summary: We've been very pleased with this unit. Using it in our car and motor home. The unit has worked as advertised and hasn't given us any trouble. Particularly like the large screen. This is the third Garmin that we've owned, and although all have been good, this is real the best.
Summary: I bought this over a year ago and its still running strong. I replaced my old Garmin with this one and it is heads and shoulders better than my old one. My favorite thing being the speed limit indicator and the lane guidance. The only thing that annoyed me is as soon as I updated the map it was out of hard drive space so I need to buy a sd card for it.
Summary: I use my Garmin for both my motorcycle and my Jeep Wrangler. It works well for both with the suction mount sticking to the gas tank paint on the bike and the windshield on the Jeep. My only complaint, and it's almost petty, is that when I put the unit in my pocket to use later, the on/off button gets pushed too easily and it runs the battery down. To solve the problem I put a piece of tape over the button to protect it whenever I put the unit in my pocket.
