It is not any better. It directed me to a supercharger for a zero 0 minute charge on Friday. Yesterday after leaving Kingman with estimate 30% SOC remaining upon arrival at Wickenburg it decided to re route back to Kingman for additional charging. Cancelled my planned route home and then routed directly to Wockenburg to solve the problem. Still needs a lot of work.
Funny, yesterday (for me too) for the first time that very same error did NOT happen - on the way up the hill East of Kingman on I-40?
It did, however, recalculate and mis-estimate the distance remaining while 30-60 miles west of Needles. There's still that "Ugh" feeling of seeing your distance spontaneously double, and warning that you have -3% charge to get there; before it self-corrects outside of 20 miles.
I only use the car's Nav for SC to SC, and in-city with a grain of salt. I never trust the "You have enough energy to continue on your trip" thing, because on the couple times that I have, I have hit Zero before arrival. I hate hitting zero at night, in the desert with my kid in the car. And NEVER, repeat, Never let it route you off the freeway onto surface roads during rush hour, DAMHIK. I'm not even gonna experiment with that one for 7.0
I'[m guessing the engineers who developed 6.2 are the ones who ended up at Apple? ;-)
