I have not used my navi much mainly because my vss wire was not hooked up. I decided to hook it up today and my vehicle dynamics finally started to work. One thing I noticed is I will be driving north and it shows my tuck going south, complete oposite. Any way to fix this? The maps does not seem to be exact also. When I turn a corner and go on to a new street the map jumps to my location. Any way to callebrate it?

Where is your antenna?

Top of truck, towards the back.

Problem might be fixed. The more driving I do it seems like it is more accurate. I will see how it is in a few days.

It will learn the more you drive. You can see how far along it is in the process by going into the system settings... it will give you 3D, speed, distance, etc... It took my D3 a good 3k miles before it filled all the bars but it was dead on accurate.
