Hey guys. I recently purchased a fpv f6 2007 ute that has factory sat nav from asl. When I power it it comes up with an error window. Im assuming that it needs an updated sd card. Ive tried a search came up with nothing. I contacted asl and was told to come down to atleast diagnose the problem. After 35 min drive I was turned away like they didnt want to know about it. Ive contacted ford and they dont know about it. So now im stuck and would really like to get it working. Please help
