Anyway, I think you meant it's useless for you then, because I, for example, have nothing against connecting over gprs or 3g to get a fix.
You will most likely find that most spedos actually clock you 5% faster than your true speed to avoid litigation against manufacturers due to speed fines incurred by inaccurate speedos.

Try going 130mph on yer speedo and then check your satnav, chances are you will be doing 120ish real speed.

fater you go the bigger the discrepency not entirely useless app
