Now for the second time my Nav in the 2006 A6 disappeared. Had this problem before and the dealer took care of it. Is it just a loose connector on the CD or do I have to take it in to have them re-boot it's little brain.

Thanks for any ideas.

you have original Audi literature for the radio/nav unit (security code in there)?
maybe a battery disconnect for 5 mins would help, but you may need the radio code after.

 

Eject the DVD wipe it off with a cotton towel and pop it back in. I bet you will be good to go.
