Whilst swapping the old unit, I think I accidently earthed a loose cable (I think either tel mute or some other wire)
Something went pop behing the dash and I have no power to the constant 12v feed. (The ingition live still has power with the ignition turned on)
I've checked fuse number 1, and every other fuse! But can't find the problem.
Only other thing affected is the interior lights dont come on when I open the doors, but can still be switched on.
Anyone got any ideas?
