Audio gateway never sleeps and drains battery. Gateway now completely failed and dealership wants $2,295.00 (not inducing labor) to fix it.
No audio/phone/navy off and on...
No audio. Only an odd "tick" "Tick" "Tick tick" sound alternating from each speaker. Command unit displays fine, satnav, radio, etc, but no sound at all other than that described above.
Radio was going in and out, just shutting off coming back own for about 2 weeks and finally just went completely out...strange thing is,I had no issues until after I had my B service done at the dealer...Uhmmm
No sound, radio, CD, phone. Everything else works fine, Navigation, system settings... etc.,
No sound or blue tooth phone voice. Appears it is a Gateway Module problem. $800 to install new gateway.
No audio, no nav display, no cell phone funtion
Lose of sound from stereo also phone and auto headlights not working. Ride safe not working check all lights warning. Have taken car to Mercedes 2 times can't duplicate problem
Command center failed only one radio station with volume control No nav,telephone,cd, Occured last week when outside tempature was unusually cold
Command goes out periodically, Comes on eventually, but is becoming a problem. Hate to pay MORE money for something that sounds like a common problem with MB
