I saw that you are the experienced guys on the net with GM cars. I live in germany and just got an 2009 yukon dneali with navigation and rear seat entetainment and premium bose system with center speaker in the dashboard.
Due to the european maps which been missing and the European frequencies (we are using also the odd 98.5, 98,7 etc , i want to exchange my orignal headunit against an oem DVD navigation. Can anybody help with the wire configuration on the back of my headunit. (4 connectors) tried a oem but the premium bose amp was not awaking. me was explained that my headunit with factory navigation has an different wire configuration as an headunit without the navigation feature

any heal is apreciated

greetings from bavaria Germany
