Old thread, but my current issue.

Was trying to run a GPS receiver on the dash board. Well after trying five different receivers, I could not get one which locked in a reasonable amount of time. Most would not lock in twenty minutes.

Opened a signal strength app and measured the signal on the dash as compared to outside the car and the signal was HALF. 48 outside and 23 on the dash. Locked within seconds outside the car
