what is your navigation doing. the d3 doesnt have a hardrive so you need a navigation disk. if it has a disk i would check to make sure that you have the gps antenna hooked up. if everything is right i would say contact who you bought the truck from and figure out where they got that deck. you can have it sent into pioneer if somethings wrong. as for the xm im not to sure about that. i dont use xm. i would say maybe you need to sign up for it and im pretty sure they will charge you monthly for service.

What kind of mileage are you guys getting? Mine is showing 16 MPG now, but last night I got it up to 19 MPG on the freeway. I have the SCT Xcalibrator 2 and it is on the performance tune.

Dont trust the in dash readings, they are usually off buy quite a bit. To get an honest figure you have to hand calculate your mileage.
