My apologies for being confusing - this is a learning experience for me too.
No no, you are not, you are parsing and analyzing things nicely, it's the information behind that makes me puzzled. My learning curve is getting harder every year.
I really would love the HUD speed on my windscreen, without only the support from GPS. Combination of both of them, OBD and GPS, maybe even helps to calculate estimate tyre wearing (is that a correct word?) at the same time.
Cheers,
Kari
