Hi,

I have a 2008 MBZ S550, ALL 4 Windows went down by itself and the car started to honk by itself....

Might any of you know if its a reset issue which can be done without taking the car to a dealer? Whats the problem?

Has any of you experianced such problem?

THanks

I have a similar problem with my 2008 SL550. Every few months or so I will walk up to the car while it is locked and unlock the car. BAM, the radio turns on and will not turn off unless i put the key in the ignition, turn to the right (without having to start the vehicle) and then turn back off and remove key.

It's annoying, but it only happens on occasion. My suspicion is the aftermarket viseeo MB-3 phone adapter (to use phone via bluetooth in vehicle).

I won't know for sure until i have it checked out.

Do you have an aftermarket phone/bluetooth adapter as well?
