Is anyone else having problems with Google Navigation losing the GPS signal on their Thunderbolt while navigating? I drive a tractor-trailer for a living, and I use Google Navigation for turn-by-turn directions to my deliveries. I migrated to the HTC Thunderbolt from a Motorola Droid X and had no problems with Google Nav on that phone (well, O.K., it would occasionally lose the GPS signal, but that was far and few between!), but when I'm navigating on the Thunderbolt, it loses the GPS signal at least once during my trip (and sometimes several times)! When this happens, Google Nav just sits there saying "searching for GPS" and will sit there like that all day long, if I let it. The only way to get it working again is to cancel the Navigation and then start it over again (I'm NOT talking about closing the Google Navigation program and reopening it, I just mean ending that particular trip's navigation and then restarting it). I have my Wi-Fi enabled during my navigation sessions as Google Navigation prompts me to do to improve location accuracy, but this still happens with regularity. I can expect it to lose the GPS signal at least once during my trip (my trips average 250-500 miles in length), and sometimes several times. This is frustrating and can, at times, be downright dangerous (if I'm, say, in downtown Chicago in heavy traffic going to a place I've never been before in a tractor and 53' trailer)!
Is there something wrong with my Thunderbolt, or are others experiencing this issue?
Thanks,
Dennis
