he is a former dealer tech that went on his own.

For years he has been saving technicians butts out of electrical problem car jambs.
His main money maker is installing factory and aftermarket gadgets on highline cars, mainly mercedes since he knows them so well.

If it's a gadget , he can make it work, he is literally the McGiver of Mercedes benz.

I worked with him at the dealership for years side by side, and I worked with him full time when he left the dealership.
We did alot of work for dealerships installing factory and aftermarket gadgets, and installing things in the new cars that Mercedes said was impossible, and was not available.
He has a storage facility of old mercedes radios, amps, fixtures, gadgets. doo dads and flippendivets, and also cd magazines, changers and what nots.

This dude is famous here in Atlanta, oh , he is also my brother in law.
yeah, so he probably has tons of those magazines for your changer.

Tell him John sent you.
