Hmmm, maybe this isn't the right place to post this, but I've got a bit of a glitch in my CD track changing via the < or > buttons on the bottom of the number pad. Seems that being in trip data display mode sometimes renders this feature inoperable. If I toggle to another mode then back to trip data display, the track changing will work all right. Everything else is fine, so I'm more than a little hesitant to take it in for "service", especially after reading the postings in this thread. Seems the less human intevntion the better!
