I have a BF XR6 with a colour screen and the ASL DVD interface through the sat nav multipin plug in the
ICC base .
Occasionally there is a clicking (relay )in the right kick panel and the
ICC screen goes black (switches off) . Comes straight back on but sometimes clicks off and on a few times before setting down .
Also has factory Bluetooth interface for the phone .
After screen comes back on it behaves as if just powered up where the Bluetooth resets and the screen shows the "media" wording briefly .
I'm tipping a faulty earth but have you any idea where I should start looking . That is where is the earth point for the auxiliaries .
May not be connected but external mirror switch has the same effect on the
ICC if you try to operate the mirror adjustment .
