That worked for me. I cleared it in both the phone and the car. Then I watched the screen when I told it to sync contacts. Sure enough, the phone asked me to approve the sending of my contacts. Once I did that, it worked great! Thanks for sharing!
I had the same problem with the new Razr Maxx I got this weekend. I have a Toyota Prius. I will delete the pairing on both the phone and the car and resync it so that I can see if it asks me for permission to transfer. Thanks for the idea!
