So driving into work today was listening to an audio book through the aux port as usual. when I turned car off and pulled the key the maps stayed up rather than turning off as is usual. I then turned off the radio, but thought that was odd and tried to turn it back on. AMG splash screen comes up and stays nothing else. I figure later on today I will just pull the fuses and see if that resets things. has anyone else seen this? and if so what was the fix?

So seems the changer had a hiccup. Audio gateway wasn't seeing it. And the changer open button didn't do anything. Pulled the F028 fuse and replaced. Changer started operating properly and radio started up

In the trunk on the left hand side , remove fuse #6 from rear SAM wait a minute or so, then replace. You will remove and restore power and as such clear a possible communication error:

- power-off head unit
- remove the key
- remove fuse #6 (inspect condition) for several minutes
- replace fuse
- insert your key and turn to position 1 (do power-on head unit)
- reset factory setting in your cluster (i.e.: outside temperature)
- power-on head unit

I've had this happen 4 times since I've had the car. There was a tip to remove the fuse in another thread where others were having the same problem. It worked but I'm still not sure what the cause is. In the meantime, pulling the fuse will do the trick.
