In advance, thanks for any ideas or suggestions. I have a 2012 TL Tech where the bluetooth sees the phone, allows it to install. It works fine for a few hours. When i come back to the car, the phone is "lost", in that it does not connect with the car's unit. The car still has my i-phone 4 on it's list, but it is unable to connect. If I turn the bluetooth off on the phone, then turn it on again, it sees it and it works. Dealership hasn't been that helpful. I have upgraded my phone to the latest OS (5.1), had an Apple store check the phone (I was told the bluetooth worked fine, after they ran a few tests). Anyone have any suggestions? Thanks so much.
