Hi, I have tried searching the forum but to no find of answers of what I'm looking for. I have a 2012 A4 Avant FL with factory fitted MMI 3g B_Nav, I have since bought a MMI 3g H_Nav unit along with the 7" screen and contol console. I have noticed that my current screen has a white LVDS fakra connector and the 7" screen has a black connector. Is it only a case of purchasing a patch lead to make the connection correct and then the system will work (minus the CP removal)? Or is there other loom modifications i require to make.? TIA Joe
