No, I updated it with correct version HN+_EU_AU3G_K0942_3_(A4-A5-Q5-Q7).
But after the SW update it works good. The problem comes only after the Navigation update.

Audi A5 2012 MMI 3GP, after install the 942FW and the 6.24map. The navigation works perfectly, but the main unit not communicating anymore with the car. No Clock, No oil level, No AC, etc.
I recode all units with vcds (AC, 5F, CE, 46) but nothing changed.
What can be the problem?

Thanks

You sure, you have not checked user definied mode in green hidden menu and flashed your unit to a MU9110 with Software from A6 A7 A8 ?
Otherwhise you have played with the car protocols in the green menu under car/carcodingvehicle under "vehicle model line", but
when you did first thing you have to bring back your unit with right firmware for a4 a5 q5 q7!

You can see under softwareversion information if there is standing HN+_AU or HN+_AU3G _.... you need the AU3G Version the other is wrong.
