When using Visiual GPS I get an average of 32-40 on the bars once I get a position fix. What sort of signal does anybody else get? I'm conviced I got a better signal before I tinted the windows. I think this may be the reason it takes so long to get a position fix.

Also If I want to get another unit that picks up better which unit should I go for, the new Haicom 204? or another make entirely?
