I just got a brand new '04 Mobius LSV. I love it, but within the first week, perfect pass was not working properly. Mostly, it would just freak out and display # signs and ????? (question marks). So when I took it to the dealer for service, they checked it and said they tightened all connections, etc. So now, it works, but only some of the time! One day it will work fine, then another it will just not display the speed. It seems very fickle...has anyone else had this problem?
