If you run across the schematic for inside the stereo unit could you post them . I designed a 2 channel Vacuum Tube ( Valve ) Amplifier ( hidden transformers ) to set on Penelope's dash for I came with a way to develop 400 volts AC to run it with a smooth waveform mechanical generator . I'll take out the millivolt signal before the Toshiba TA8221 power amplifiers before it's distorted . Lady Penelope is my car , I'm her engineer

The closest I have come to getting the schematic for inside is from the tech guy who is going to repair the unit itself, Joe. Quote-
"I do have a schematic diagram but Alpine are very strict with distribution of those manuals.
They do not want any of these manuals released to the public.
If they can tell me the area they would like to modify, I can send them the required pages.
It sounds like maybe they are trying to make you an auxiliary input?
Would they probably be intercepting a source before the EVC chip? Maybe I can send them that part of the circuit to help."
This scared off the other guy who was going to integrate the bluetooth unit Aurora BTU-1, into the system. As far as I can figure out, Alpine are very secretive on these schematics. They told me -"Alpine do not distribute any OEM product information."
