Fun application...I hope the next version (1.2) can utilize the GPS for more accuracy. It is fun but wasn't too accurate for me (BMW has scattered many warnings stating that the numbers are not accurate, and the numbers were close to what similar iPhone apps have given me).
I went around E-Town Raceway Park, found a somewhat flat closed area and did a run. My 9500ix showed 78mph before it registered as hitting 60mph.
I had it calibrated standing up perfectly and then taped it to my CD player. lol
