Hi Chip, I've had good fixes with up to 5 to 7 satellites with the EarthMate when outside, and still can lose it when I enter the bus. I thought it would help to acquire a good signal when outside, but it doesn't always hold.

I have a relatively new vehicle, and it indeed does have the metalic coating used for window tinting, on the sunroof and the rear windows, but not on the front and 2 front/side windows, so I have to sit in the front passenger seat to use my EarthMate. One other thing worth mentioning; standing still while obtaining your original coldstart fix will yield a fix *much* quicker than trying to get one while moving (say in a bus). This may improve matters somewhat as you suggest if you stand still outside the bus first to get a good fix, and then board.
