Just installed the Alpine IDA-X001 head unit into my car. I connected the phone via the high speed cable, the i-phone got hot... Well i read in many posts that this is normal, so i started playing some of the stored tunes. After about two songs the i-phone switched off. I disconnected it from the head unit, I could re-start the i-phone simply by pressing the top button. I connected the phone again, i selected another song on the radio, it played for 5 seconds, the phone went dead again.... That was it, no more reaction. Can not restart the phone. I tried all tricks, holding both buttons, toggling the mute switch on the side... nothing.... The i-phone is dead...... Anybody else had this problem before? My phone was running fine without any issues since December 2007.
