    Just wanted to report that I've experienced serious GPS lock issues while using the 640XL. It doesn't happen all the time, and it usually happens about 15-20 minutes into the driving, so if you haven't used GPS navigation for more than that, you probably haven't seen it. What happens is as I am driving on the freeway, all of sudden it loses GPS lock, then reacquires the lock seconds later, but it says I'm off the freeway about 100 meters away going in a completely different direction. Then it tries to reroute, and at this point, it starts to spin left, spin right, like it's confused, all the while I'm still driving on the freeway. It doesn't recover either, even when we gave it about 5 minutes of trying to sort itself out, eventually I have to turn the phone off and on again, and then it seems to return to normal. I've experienced this numerous times now on both 640 XL's that I have, with both Here Drive+ and Navigon (which also uses Here Maps), and I've never experienced this with the Lumia 1520 or 925, which leads me to believe it's a bug specific to the 640XL's software/hardware. Anyway else experience this?

    This is strange, I have no issue so far with the GPS on Here drive +. I will double check tomorrow (2 hours journey) and let you know.
