Audi Concert schematic

[teknobod]

My original Audi Concert made by Matsushita (Model CQ-LA 1610) has a tuner problem.
Does anyone know where I may be able to get a schematic for this unit as I do not want to buy another of the troublesome Blaupunkt models from Ebay (after someone was misleading about the problem it had ).
I may try Panasonic if all else fails, but from my days as a car audio repair technician I seem to recall that Panasonic UK do not usually keep service information for OEM equipment.

Cheers

Andy
