W211 headunit install questions
I've just bought an Alpine iLX-W650E headunit to fit into my E280.
Aerpro makes a number of different patch leads. I'm unsure as to what I need. See https://aerpro.com/vehicles/mercedes...w211-2002-2009
What is Quadlock compared to Fibre-Optic? I would like to retain the steering wheel controls.
Any advice appreciated.
If I could tell myself what is needed before hand, I'll save myself $80
