Ok I searched and found an answer that kind of answered what I was looking for. I was wondering if anyone else is having issues using the messaging system and their iPhone 4s. When I have the phone connected through bt and I hit messages it says its downloading, sometimes, but I have never gotten a single message or seen the messaging system. My next step is to take the vehicle to the dealership and see if they can help but...anyone having the same issue? Any ideas?
