Hello! I am planning on replacing my AUDIO 20 head unit with a kenwood DDX 4021BT, basically a Bluetooth head unit. The reason for the choice of unit is simple: 1. Kenwood make a fitting kit that should (?) ensure a professional and seemless finished result (CAW-2190-18-RT) 2. Ken wood make an integration kit for the steering wheel controls. (CCW-CCAMME3 / CAW-CANUN1) based on the assumption that my vehicle has ISO and not Fakra connections? Have any of you performed a similar installation? Is it as simple as it would seem to be? (ie no soldering / cutting of wires) Is the assumption of iso as oppose to fakra correct in a vehicle of this age? Is there anything else I need to purchase before installing? Any tips greatfully received!
