All,

So I did the nav hack a few weeks ago, and everything seems to run smoothly. Can watch DVDs, enter menus, navigation works etc.

The only problem is that the map is a little bit jumpy every so often, and the map doesn't seem to track completely straight all the time.

The functionality is still ok and I get directions etc.

So if I have my map direction pointing in the direction I'm going and not north, the display instead of going straight up might be tilted to the left or to the right by 5-10 degrees or so.

It might adjust itself, but then go back to being tilted. Its not a big problem but kind of annoying. Did I do something wrong? Or do I need to recalibrate my GPS?

I also installed a new cd changer at the same time, because my mark levinson changer was busted, would that have affected anything?

Any help is appreciated.
