iGo8 My Car/Compass/Icon "Spins in Place" While Stopped at Traffic Lights

Has anyone else experienced this phenomenon? While stationary; be it stopped at stop signs, traffic lights, or in my driveway, etc. my iGo map & compass "spins" as if it cannot determine my current facing. Once I'm in motion, it straightens out & points to the correct heading (with the occasional random map rotation now & then).
Could it be an antenna issue? Im using a 2Din aftermarket sound deck with a wired antenna.
Any other suggestions?


Thanks!

It may be just that, a wierd anntenna ;)
Have you tried moving anttenna?

I also get that from time to time, cloud cover, weak sig (buildings etc)

All my devices do this occasionally, The GPS signals are not that accurate, especially where buildings are nearby, When the GPS receiver takes a reading it may briefly pick up a reflection from a nearby building and the software may think you've moved slighty, and the display moves accordingly.

Yeah, I wouldn't mind it if it was an occasional problem, but my little car icon literally spins like a top every time I stop at an intersection. It's quite maddening.
