winston61 Posted December 27, 2006 Share Posted December 27, 2006 Hello to all- Does anyone have GPS reception problems through the windows of General Motors trucks and SUVs? When I drive my bosses Suburban my garmin does not seem to perform as well. Anyone else? Quote Link to comment
+ICHTHYS Posted December 27, 2006 Share Posted December 27, 2006 Depends on the GPS and where in the vehicle it is located. Quote Link to comment
+DyverDown Posted December 28, 2006 Share Posted December 28, 2006 Depends on the GPS and where in the vehicle it is located. Some vehicle windows also have metallic coating for UV protection... it seriously effects GPSr reception inside vehicles. DD Quote Link to comment
montyxc Posted December 28, 2006 Share Posted December 28, 2006 Depends on the GPS and where in the vehicle it is located. Some vehicle windows also have metallic coating for UV protection... it seriously effects GPSr reception inside vehicles. DD I just used my venture cx in our Safari van over the weekend and had 8ft. accuracy. Moving it to the middle of the car away from the windows did seriously limit the signal, but overall, I was surprised how well it worked. I just got it a week ago and was afraid of it not working in the car. Quote Link to comment

+JDandDD Posted December 29, 2006 Share Posted December 29, 2006 We've used ours in our GM SUV without any problems as long as there is vision to at least two windows from where you are sitting. Only one window still works but since you can only see part of the sky there are less satellites available for a fix. We have Garmins and Magellans and both work, even my Forerunner 305 strapped to my wrist works. JD Quote Link to comment

+Sputnik 57 Posted December 29, 2006 Share Posted December 29, 2006 One list of problem vehicles is here. The same thing that messes up GPS reception also messes up toll tags. I didn't see any GM trucks on that list. Quote Link to comment
+GeekBoy.from.Illinois Posted December 30, 2006 Share Posted December 30, 2006 I mount my Garmin GPSMap 60CSx on a "vent mount" and I lay my Magellan eXplorist 600 on the dash or on the passenger's seat in my 2002 GMC Sonoma (pick-up) and do the same in our 2002 Pontiac Montana. In the Montana, I also place the Magellan in the little holder/alcove in the dash near my left knee. All of our units work fine where they are placed, and seem to get strong signals on a full selection of satellites. Quote Link to comment
+BBM&J Posted January 6, 2007 Share Posted January 6, 2007 We have a '00 Olds Silhouette that has the coating in the windshield and none of my garmins (legend, vista, 60cs and geko 201) work on the dash. Will work sometimes in lap or by a side window. Quote Link to comment

+willy1970 Posted January 7, 2007 Share Posted January 7, 2007 eTrex Legend -> '04 Silverado w/topper -> 8-20 ft. accuracy (usually) -Jeff Quote Link to comment
+augmarenne Posted January 7, 2007 Share Posted January 7, 2007 I have a 2001 GMC Jimmy and have no problem. My wife can even hold our Magellan eXplorist 500 in her had while were moving. I do however, have a sun roof so that may make a difference. Quote Link to comment
+Renegade Knight Posted January 7, 2007 Share Posted January 7, 2007 (edited) One list of problem vehicles is here. The same thing that messes up GPS reception also messes up toll tags. I didn't see any GM trucks on that list. That list has my Montana on it and my Montana does have the metallic layer in the windshield that would block GPS signals. You can see the film. On the montana the top of the window has about 4" or so that doesn't have the film. You can see the line. Edited January 7, 2007 by Renegade Knight Quote Link to comment
+GPS-Geek Posted January 15, 2007 Share Posted January 15, 2007 My 2001 Chevy Venture will not read a single satelite from my 60CS. I have to hold it directly to the glass on the side window. I'm looking into buying an external antenna for around $15 on e-bay. Quote Link to comment
