Hi I want to know if i can mount the gps antenna to the windshield or does it have to be mounted somewhere on the outside of the car. Thanks

i have mine sitting on my dash where it meets the windshield. no issues for me. it has been suggested though that you use the small metal plate under the antenna

mine is INSIDE my dash, and it still works great

As long as it's right-side up, horizontal, and there's no metal between the antenna and the sky..

Thanks a lot for the info.
