car stereo repair manual?

[fuzzysig]

does anyone have a link to a car stereo repair manual?
I looked everywhere and all I find is the basic troubleshooting of car stereo system which is nothing to do with actual head unit repair and troubleshooting.

or maybe a service manual for any of the newer headunits?

I have another thread about it
Kw-nt800hdt in the repair section
Im mostly looking for something to read to understand how they work and how to troubleshoot the car stereos specifically
And hownto understand the circuit board layout etc.
I would assume any of the newer indash or cd player service manuals would still be helpful to read.
