Mmi goes off for a few seconds when playing rado or cd

You got a defective new unit??

buy a new cd on eBay for lot less

INSTALL A MANUAL CUT OFF SWITCH FOR THE AMP AND SAT RADIO .THEN SEE IF IT STILL DOES IT IF SO ITS NOT THEM PARTS

Sorry to state the obvious, bit just in case, have you checked to be sure the screen is turned on? Press and hold the volume knob for a few seconds. There is also a display off button on the dash to rt. of the display unit.

If all are on, try resetting the unit:

try a cd lens cleaner from tandy

No solution, same problem, but had many strange moments: 4 months ago during 100 kms or so it stopped, then suddenly came back, and worked ever since. A few days ago, it started happening again: NAV stuck, then radio dead, and gradually the rest disappeared. I did a Reset, and since that moment I see the intro-screen and then it goes black. Hitting the TEL button is somehow also a Reset...

Do the previous 2 posters have anything to report on this matter? It would be VERY welcome!

Thanks,
Jeff

One thing have you tried to pull the CD out?

The dealer fixes everything...at a very steep price if not under warranty. If out of warranty i suggest you look into aftermarket stereos. Try a reputable stereo shop that won't rip you off.

Your most (fiber optic) system is inoperative. Its most likely your CD player and the bluetooth is an update issue, if it doesn't take the update then you need to replace your telephone transceiver.
