I have a Viano CDI Ambiente 2006 with a phone cradle mounted on the dash near the steering. It is factory built and is the right connector for the Visee0 MB-2. I just bought a Viseeo MB-2 and connected it to the car cradle. No power to the unit. I tested the unit by connecting it to my PC and it picked up the phone, paired the devices. So the unit works. I called mercedes exeter to ask them if they kew anything about it as i read on another forum that sometimes those units were not connected (wired). All i got from them is: "Sorry, I don't know, we don't do much with Vianos.". Then the next one was "£120.00 for looking". I'm gutted. Once again I am stuck with £160.00 worth of kit, and no means to make it work. Anybody with an answer?
