I have a goodyear gps>gy120. I keep getting error code calnot.exe, will not let me use my screen, after several attempts to call the electronic company, the NCC, brooklyn new york, they still haven"yt returned my call after I left messages explaining the problem.and there are no updates at all for the gps when they say go update it, I would like to speak to some one regarding this matter. or get refunded for gps, , I have original receipts. but it seems like no one wants to correspond with me, I also emailed goodyear with this problem, and no responce, so this is my last attempt, before I have to go over everyone"s head, thankyou, Mark Rinehamer.
