[dwind21]

HELP!!!! It was so random....I went to my buddies house, hung out for a few hours, got into my truck, pulled off and then suddenly it cut off....and started back over and kept doing it every 5 minutes. When i got to the system settings, it kept telling me there was no map, but i run version 2.008 and have been running it since it came out....The warranty people are talking 4 weeks or more, no way!!! I been without it for 2 days now. I need the original system files so i can reboot it, then just go ahead and upgrade it to system 3.....but this is driving me nuts. I saw one guy who had it uploaded or backed up somewhere and I went to download it and turns out i was just 2 days to late....he took it down on the 5th ..........please help!!!!!!!!!!
