Summary: The Satellite reception is poor. Sometime you have to run for a while from your starting point before you can pick up satellite signal. Also, sometimes you lost the satellite signal while driving. It bothers me and I am not happy about poor satellite reception.
Summary: I have just returned from two long trips, and it took about that amount of time to really understand how to use this device to best effect... However, on the second trip (6000 miles) the thing developed heat prostration, while travelling in Texas; I had it mounted on the dash, in direct sunlight... It became sluggish to inform at intersections, turns, etc., until after you are at or past the decision point...
Summary: After setting up for Avoidances the routing function still gets its own mind as how you should go. This unit wanted me to U turn and kept insisting on it for the first ten miles of a 20 mile direct route home from the store. When I think of using it on a long trip to a new town the thought gets real scary. Maybe their Map Provider needs to Make trip to the western states. All my Garmin units seem to have the same type of problem.
Summary: I had to return the unit because the ball-and-socket joint did not hold. The unit fell down to the floor with the slightest touch. Yes, I do know how to install the ball-and-socket joint because I also have the 2597 model and it works fine. The reason for the 7 inch screen is to support an option rear-view camera. The 7 inch screen is roughly the size of what would be provided by a navigation system sold by automobile manufacturers. Some like it, some not.
Summary: I like the size of the unit - great for older eyes but the unit died after just weeks and one hour of real use - Amazon was great and took care of the matter quickly - sent me new unit (hope this one works out better) and I sent the dead unit back using Amazon's return UPS label. I have a Garmin nuvi for my wife and it has worked without fail for over five years - so I was disapointed with the 2797LMT.
