I have a problem with my connection, I have had to reset my phone, so deleted the paired phone and repaired, whilst pairing its keeps saying connecting error, as soon as I finish pairing on the phone it says invalid device, but the bluetooth audio connects and works (which I don't think it did previously) I have tried deleting the pair from the phone and re-pairing but no change, I can connect another phone so the system works, could the problem be the system is confused in some way as the phone was previously paired? I am reluctant to re-set the bluetooth control box, as that entails dismanteling the dash to access it.
