I have an 06 Charger R/T with the steering wheel audio/EVIC controls. I was told the other day that if you press and hold the "Compass Display" button and the "Audio Mode" button at the same time for 10 seconds, a hidden menu comes up. I tried it, and in fact it does but I don't know what the heck some of the options are; does anyone have experience with this?

THANKS
