Was not getting lap times this weekend at the PCA Club Race at Monticello. Was working fine at the last event. Evo4 and Gdash w older smartycam. Track was definitely loaded on camera and Evo4. Had 4-6 satellites but the map was all over the place, some on track, some through the infield in places where I definitely didn't drive. Tried deleting track and reinstalling, didn't help. Tried deleting all tracks and tried to add a new track while on the out lap. Said I had good GPS, then coming down the straight towards start/finish, it went away, then reappeared right near start/finish, so I pushed "ok" to add a new track, but that didn't give me lap times either. Does this sound like a bad antenna? What else could be going on? Thanks to Franklin Pray and Bob Saville for trying to help me sort it out trackside, but still unresolved.

 

It sounds like an antenna issue. Bob mentioned that the cable to the GPS was melted or something similar?

 

Thanks Matt. There was some melted insulation from an unrelated "incident", but I'm pretty sure what we saw wasn't new, and it hadn't been a problem before. That said, I am going to switch out the antennna and see if that's it. Is there a way I can test the new antenna at home? The car's not street legal.
