2002 C320 BOSE HU - Preouts?
I have searched and searched for this info and can't seem to find any answers.
I am ready to replace the HU with Pioneer AVIC-D2 and can't find the preout from HU to the amp! I looked at the back of the unit and B connector is not there or a harness for it. How is the amp getting pre out/speaker level from the HU?
Any help will be apprecaited.
