I have a 2797 LMT and use it with my Galaxy S5 with the Smartlink software. 1. Does anyone else have a Bluetooth connection problems? Sometimes I have to turn off Bluetooth and restarted because it won't connect. It see it but will not connect 2. The Bluetooth connects but long delay seeing phone book. Finally what is the top of the line Garmin GPS. I understand that the unit numbers do not mean that one is newer then the other. I want to purchase a new one and pass the 2797 onto my wife.I diffidently want a 7" screen so what is or soon to be the best unit with the most features. Thank you Dan
