In a bid to be able to have track info and control over my iPhone with my headunit (RCD510) via bluetooth I swapped the 9w2 bluetooth unit for a 9w7 unit. I now have the grand total of sweet FA happening via bluetooth ! So I went out for a drive to embarrass some BMW's. Don't know if this has been covered, it probably has but I can't find it so I will put a post up. Quick version; phone sees bluetooth, phone connects to bluetooth nothing else happens, no calls no nothing!
