My brand new iPhone 4s does not connect to the Alpine head unit every time I enter the car. My old Plam Treo, and then my deathly slow iPhone 3G connected perfectly every time. Is anybody else having issues? I have to go to settings, and reconnect the phone every time I enter the vehicle. Once connected it works fine except for Siri which broadcasts over the speakers, but cannot find the car's microphone. Anybody else have this issue?
