I've removed my RNS-E MK2 from my A4 so I can sell it and got a Concert II+ to go in its place. I've swapped over the K-Line from pins B5 -> C7 but the Concert II+ won't power on. Nothing is displayed on the screen.

Is this because I've not coded it yet to the car? I share a VCDS cable with a friend so not been able to code it yet but I would have thought the unit still would have powered on?
