My Iphone 4 will only connect when I ask it to. As did the Nokia E71 before it. I have tried upgrading the cars software but after numerous attempts and hours of the engine running (last one lasted 45mins) I have given up.
I find once connected it works ok although I have to re enter the pin in the phone everytime. No phone book or calls listed and the first incoming call doesn't come through the speakers so I have to change the setting on the front screen of the phone. All damn annoying but I have learned to live with it for now until someone suggests a fix....not Audi either at over £100 per hour
