you know how when the map is showing and you go to press MAP, and the menu comes up with 5 options, one of which is "Vehicle Dynamics"? well for some reason whenever i go to press that button, nothing happens. its like i just dont have that feature anymore. i had it a few weeks ago, then i had some audio work done and poof, i cant use it anymore. anyone have any idea how i can fix this?

When you added some audio stuff, did you disconnect the power to the headunit also? (i.e. remove the cables from the battery or pulled the harnesses out of the headunit?)

If so, your unit could be back in the "learning" stages since it was "reset" by having no power.

Was the unit bypassed? If "some audio work" caused the bypass to come loose that could be the problem.
