Installed a Kenwood KMM-BT322U head unit. I can pair my iPhone with it just fine but then it will immediately disconnect and will not reconnect. Ive tried having it forget the device and then pair it again and it still pairs fine but does the same thing. If i change the source to BT audio, it will not connect. If I try and connect via my BT setting on my iPhone, still will not connect. Any ideas?
