Hi! Newb installer here for a N2 install into my 1997 BMW 318ti. I searched this and other forums for an answer to my question. Found no direct answers, so let me ask here.
The base issue is no sound from the N2 HU. I have the N2 and brain wired into a harness connector to the factory harness. The Stock BMW amp is in place with the stock wiring. I believe my issue is the AVIC wiring has no way to interface with the BMW amp.
The wiring connector addresses most of the wiring save Yellow/Black, Blue/white(amp) and 2nd black wire. No additional connector to interface with the white
