Summary: It works really well so far except for some roads around where I live . I wish they would correct the error. One road is paved but they call it unpaved road. Another road it tells me to turn on does not go all the thru like it shows on its map.
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...
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.
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.
Summary: I like the size. Struggling to pick up signal in Manhattan. I have used for over 10 years other garmin nuvis and none had this problem of picking up signal in NYC!!! Resolution is poor compared to other nuvis.
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.
Summary: Great product with great support from Crutchfield. No support from Garmin. At time of purchase tried to register unit with Garmin through "Garmin Express" and download updates. Would not recognize unit, had to delete and re-enter. Then map updates still failed.
Some Issues With Charging and some quirks in the electronics

Summary: I bought two of these units for my wife and me, thinking that the larger screen would make it easier to see without our reading glasses - I would say that the larger screen is only marginally better and not worth the extra money.
