The sevice manager said they may have to pick up the power from the boot, so this would increase the price as additional manhours required. I've had it done on my last three BM's and if memory (fading with age) serves me right it was approx £150, which is not cheap but far better than trailing wires all over the dash
Thanks for that, yes I've had it done in my last 3 BMWs also funnily enough! It will be a bit of a job getting power from the boot though if they need to, lots of trim removed and potential for rattles etc.! Do you know where they'd route the cable to get it back to the boot?
