Got yourself a "Christine" there, eh?

Ok another idea. Pull all the fuses for the nav. All of them. Search here on how to install Aux cable. Instructions have all the fuses listed. Pull them all, wait a bit, and put them back in.

Yea I concur with Slick. The module seems like it is flipping out. Try resetting these modules and trying that method first.

And please update your signature.

Ok, i will try the fuse thing and report back. Sorry bout the signature. Ive been under my 500 sl all day changing suspension. Now, it should be ok!

Ohhh Faaaaa, 500SL, god bless ya bud! lol

Try keeping the tape in and shutoff the car with tape in and restart.

Does it happen if you reset everything and turn the car off momentarily then on or only on starts after a long time off?

It happens when i open the door actually. Tape in or out.

E53 opens what?

I am happy to report the problem was solved by removing the fuses and resetting the unit as per Slick's suggestion. Just in case someone has the same trouble heres what to do: open your glovebox. on the roof of the glove box is a fusebox, there are tabs on either side, push those in and the panel folds down revealing a rather sizable fuse box. Remove fuse #7. Now got to the boot or trunk as we say in USA. On the right side there is a compartment that can be removed very easily, look inside and at the top there is a smaller fuse box. Remove fuses 72,73,74,75. Wait 5 to 10 minutes, put all fuses back in the order they were taken out. Turn your garden hose on, spray a healthy stream directly in the air and stand under it with your face pointed upwards. Start your X and the radio should be working fine. Thank you for everyones responses especially SlickGT1!!

Good stuff bud. Now you are in my club. I can't even mention how many little problems I've fixed by pulling fuses. Bluetooth, trunk softclose, nav froze. Also for the future keep in mind the relays. Those bastards stick from time to time too. Even pulling fuses does nothing. Pulling the relay, and back in, fixed quite a few other problems for me.
