I was surprised when I noticed the speedometer reading exactly matched a handheld GPS reading. That made me think the speedometer uses the GPS for speed input. Is this indeed so or just coincidence?

I was just doing some Google searches for a parameter to extend or eliminate the rear window heater time to off delay when I stumbled into the following two items available on the one series.

True speed in digital speedometer KOMBI BC_DIGITAL_V_KORREKTUR nicht_aktiv = true speed
True speed in analog speedometer KOMBI BC_V_KORRECTUR nicht_aktiv = true speed

Does anyone know if these parameters exist on the F25?

I am waiting for my cable to arrive so I can activate the TPM pressure/temps and digital speed indication. It would be nice if both the digital and analog speedometer read the accurate speed from the GPS.
