Have done a search and couldn't find an existing thread with the same problem... so here goes... As per the title, my iPhone 4 (4.3.2) is currently paired to my MY11 Subaru Impreza's head unit... which works great to receive phone calls. However - it also seems as soon as it connects, the phone starts playing music (via BT-Audio) even if I don't have BT-A selected as the input on the head unit. This of course sucks the battery down something rotten. There's a known problem with the iPhone 4 and the Subaru HU in that it won't get contacts off the phone (although apparently works ok with iPhone 3's), however noone at the dealership had any idea about this BT-A problem. I've tried un-pairing and re-pairing it, however it seems the HU has the BT-A and phone side of things intertwined. Thoughts? Surely I can stop the phone from automatically starting to play music when it pairs to the head unit?
