UMI-Bluetooth Unavailable!
Dear all,

Does anyone know what to do, when the UMI-bluetooth is unavailable. Mine just randomly goes unavailable and comes back on whenever it feels like.

I would please want to know:

1. what causes that to happen?
2. what can be done to restore it when it happens.

Regards!

2011 GLK350
Same issue
Did you ever find a solution to this issue? I'm having the same problem in my 2011 GLK350. Telephone Bluetooth works perfectly 100% of the time. Umi however works good sometimes but other times my audio/nav screen just says "Bluetooth unavailable". No reason just randomly goes unavailable, sometimes for days at a time......
