2013 x204 COMAND has Navi button but no Nav
The head unit has a Navi button but when activated the screen message "Navigation not available" is displayed.
Is enabling Navigation an option (e.g. add the GPS antenna then enabling via engineering mode) or do I replace the head unit? Replacement seems seems odd because the button is there, but then again this is a Benz.
I am aware of the Becker plug & play unit, but that thing kinda sucks.

Also lost fuel graph from system and Bluetooth Audio music.
All happened a few day after dealer updated softwares and car reseted in the morning.
I think that in reset it lost car configuration equipment and restored original firmware
Have you solved the issue? how?
