I also have a GPS repeater - somewhere. It had a small antenna I could place on the roof or near the window and a stick for inside the car or at my desk.

That repeater worked well, but then I started switching to roof mount modules (Garmin GPS16/GPS18) or the newer BT models that work from deep within a car.

I would appreciate it if you could point me to the repeater since I've wanted to get another one.
