My GOLIVE 1535 Takes so long to get a signal and when it does it lasts for 5-10 minutes and then reboots. In my 45 minute commute, the unit reboots 2-3 times and some times it waits for the whole 45 commute to get a signal, just as I am pulling into driveway. My question is- what can I do to fix this annoying problem. I am sure someone out there has experienced this problem, a quick reply would make my day. THANKS.
