I have an 05 GXP with about 70k. Third party sold it then had to REPO, I never should have sold it. Anyways now i finnally have it back and the Speedometer doesn't work and the HUD shows a constant 0, after about 2 miles on the road the ABS and Traction control lights come on. It also says to calibrate compass but when i try i just drive in circles forever and nothing happens. I tried replaceing the VSS but no luck there, Anybody got any ideas.
