Hi,
I just acquired a 2001 DB7 Vantage with Alpine audio system and Alpine 6 CD disk changer in the trunk. The CD player does not function any more (it did until a week ago). When I select CD player as a source it says "D3 error".
I took out the disk holder, changed the CDs in the holder and put it back in, but this did not help

. Does anyone know a cure for this problem?
Thanks in advance.
