It may depend somewhat on the model. Also, the signal degrades if it has to go through walls, etc. I use a Garmin Etrex Legend that I have had for two or three years. It works fine in the car hooked to my notebook, although it does claim better accuracy when it is lying on the dash. It works in many houses, but not those with the new metal roofs. It works in an airplane as long as I hold it near the window.

My receiver is a cheaper magellan model. It doesn't work inside buildings or airplanes. Are there any receivers that work well anywhere?
