Hi I installed my D3 in my dads 07 Dodge Sprinter last year after having it in my Scion tc for about a year with no problems. for some reason now the nav arrow always points sideways, or backwards and is never correct in the position im in. I have tried recalibrating my position manually about 10 times with no success.. anyone know what else i can try? a friend of mine said to try a firmware update, but i dont think this will help...

also his AM radio catches no reception whatsoever, any help with that?

thanks in advance

You need to recalibrate the GPS. Pretty easy, search the forums for it. I dont remember the exact directions, or call Pioneer and they will walk you through it.
