Well here's the update. Turn it back on? LOL. Tracy I would never admit to that

. I tried that, the Navigation, phone, CD and all the other buttons that only my eight year old understands. Nothing. I pulled, checked and replaced the fuse with a different one. Nothing. So I check back with all of my Mercedes friends and read Gilly's post with great interest, and Tracy's with dismay. So I ran out and disconnected the battery, the negitive is pretty easy to get to, and low and behold we have tunes again

The battery was the next thing I was going to try anyway but I didn't know about the ESP. Thanks
Tracy, maybe you and Casper and the gang need to come out to Colorado for some of our 300+ days of sunshine, sounds like you have a grumpy radio.
