lambos have always been 10% off, so that 219 was 198, sooooo close, yet so far

After '08 they were only off about 5%

From my dealing with Gs they were never as bad as 10%, but still off

Hit 185ish in the Diablo, GPS said 168

Are you sure you followed the button push sequence exactly?

Push NAV, push-and-hold-5sec upper left, push-and-hold-5sec upper right.

And just to double-check -- your car has the stock nav, right? (Audi RNS-E)
