Scrollwheel stopped working on 2012 E220 for Bluetooth
Hi, I took my car in to get the maps updated and they said they couldn't do it - which is fine, but since then the scrollwheel has stopped working for the bluetooth audio. Initially the bluetooth audio didn't work at all, but I got into the admin panel (by holding hang up, # and 1 for three seconds) and turned it on.
I phoned the people that did(n't do) the work and the conversation went like this: Them: "We didn't reset or change anything, because we couldn't get into the system" Me: "but it was working, and then it stopped working after you had it" Them: "We definitely didn't reset or change anything, because we couldn't get into the system" Anyone know how to get this working? Other symptoms are that bt audio says it's not connected although it's working. I'm getting no track listings, and I said the command wheel doesn't work.
