comment 35.

I can see more than 10 satellites at any given time but I'm unable to get more than a coarse lock. In OVI maps (along with other applications I've tried) my position is around 500-800m off, and it "jumps" around the map, between two different positions at least 500m apart.

Thanks for taking the time to reply
