I got my first smart phone 2.11.14, a Motorola Droid Ultra and paired it with my car, 06 Lexus Rx400h, and everything worked fine for about 48 hrs. Then the phone stopped connecting after I would stop for gas or go into a store. Car said it was paired, phone said it was connected, but call would default to the phone, won't go through car. After several days of unpairing and repairing, I went to Verizon, and of course they say it's the car. Called Lexus Corporate, they say it should work. Called Motorola, same thing. Called Verizon, after 75 minutes, they send me a new phone. New phone works great.... until I get the new update for the 4.4 ? android operations system. Now I'm back with the same problem. Will not stay connected with car. Anyway to get rid of the new system, and back to the old that worked fine??? I hope someone can fix this.
