I have the stereo system upgrade. Just recently I can control all the front end features, but I don't get any sound.

Then on occasion I turn off the MCS and back on, and the sound transmits.

Any thoughts?

 

Not sure what you mean by "front end features", but the audio can be turned off/on by pushing the volume **** in.

 

The head unit is on, and I can select tracks or radio stations, or make a phone call, but there is no volume whatsoever. I can then go back at some later time and turn the radio on, and the volume is working again. So right now it's intermittent, but no volume is occurring more often.

I noticed that a few R53 owners had a similar problem. Thanks for the reply, RC.........
