Is anyone else's GPS having trouble tracking your location. It seems if I turn it off to save battery when I'm not using maps and I turn it back on it can't track me. It worked great when I first got it, now it seems it can't locate me as good. Could this be a software issue or hardware? I downloaded advanced task manager and whenever I want to end all the apps I do that instead of individually selecting which ones I want to end. Could this be messing something up? I really want my GPS to work, I'm also in the NYC area so for the most part I should have signal all the time.
