I just noticed that the Nav unit does not display current speed. (Is this possible?) Does anyone know how accurate the speedo is on the Cadenza relative to GPS determined speed?

Had mine checked by police radar and it was right to the MPH. Usually the speed on cars show up slower than what the speedo shows, but not on my Cadenza. it seems to be exact

Just the answer I was looking for! Thanks, Gene.

My BMW was at least 5 mph slower than GPS speed at all speeds. It will take a while to trust the speedo on the Cadenza!

I tested with app on iPhone and Cadenza shows 1-2 mph slower than app...I'm not sure how app is accurate but it was pretty straight highway with no incline

I'm not entirely sure why this is a question. What is there not to trust? The speedometer was calibrated correctly to the tire and wheel size of your vehicle. Because GPS from a satellite miles above you is a little off from what your speedo says you don't trust your car?
