I've just got an OEM Audi Bluetooth module (8P0862335F) & mic (8L1862373A) but haven't got the wiring loom. Which loom is it best to get - the Audi one, or the Kufatec one? Is there a guide anywhere on how to fit the BT module, and I need to re-code the RNS-e with VAGCOM? Any other fitting tips would be much appreciated. Oh, and are there any know issues with the 'F' module? Thanks in advance!
