Dead BOSE head unit.

My Bose head unit has just stopped working completely. Sound and display suddenly went off, then just a couple of flickers of the clock then - nothing. Fuses seem OK. Anybody know of a repairer or sensible way to replace without having to change everything? Alternatively, anyone have a (working) Bose unit for sale?

What year car?.We have some BOSE units from mk2/2.5.

 

 

Says MK3 in his signature.

I think there is a company which specialises in this if you Google for it, but it might have been Bose power amps.
