Thanks for the input, wpoll. I wasn't exactly sure...it was more like a thought on a card...stuck loosely in my "mental rolodex".
If not being able to reset to zero is bothersome...like mentioned, you can pull the negative battery cable and it will go back to zero. If you don't really use this feature...and you have to scroll through it when you're using the BC button on the end of your turn signal stalk...then just reprogram your OBC and leave DIST & ARR out of the mix. You can choose all or only the OBC features you want to appear in the instrument cluster display. There's no need to scroll through ALL of them if you don't want.
