I 2nd this, changing the system setting for the backup camera from oem to aftermarket was one of the first things I did, thought the little car on the screen was cool. :)
I believe the Moddiction unit has a trip computer in the nav software. I feel like I saw it but just didn't try it. I may check it out when I get home this evening.
Ok interesting, just asking b/c my time is correct and I manually updated the time zone in system settings the night I first powered up my Moddiction unit. The next morning, I did unplug everything so I could re-route my GPS wire, don't remember adjusting the time zone again when I powered back...
