I read over the ad and specs for the Garmin model "RV NA 77 LMT-S", looks good! Price is $300:

Noticed that it and other units need a "compatible" smart phone for full functionality. I finally found a phone number to contact Garmin Support. I asked if my cell phone is compatible and was told that Android 4.4 or above are compatible, mine is 6.0.1. I also found that my cell phone has Bluetooth 4.1 which should also be compatible.
