Must be different than mine then .  Are your clutches working or is it just the mapping that is not working?  I did have a mapping issue with the receiver losing its sense of direction that caused everything to skip and act goofy.

If you have the latest updates you should be able to select softkey "B" (Guidance Button) under the GS2 Pro tab - and in the middle of the screen there is a tractor icon with an arrow pointing forwards or backwards.  Make sure it is pointing forwards.
