Does anyone know how to reset all the codes that pop up in the nav?

 

you mean the radio and nav codes....i dont know if thats even possible....

 

You mean the messages? hit map cancel and one more button cant remember off the top of my head but its next to the map guide..

Go to the last button it says XM something.. Hit Xm ECU and reset data.

 

For example, I forgot to hook my air sensor back up when i installed my AEM and now i have these two codes on the nav - i don't want the dealer to see them!

I've also heard that you can pull a fuse to reset it.
