Sat and GPS aftermarket antenna placement

Recommended Posts

Would there be any reason why I could not place the antennas for an aftermarket system on the front dash? Does the windshield block any signals? Would they have to be separate from each other? I was thinking about installing underneath the center vent/speaker plate. It would have direct path through windshield ( I don't know if the mesh speaker grate would cause interference) or simply install on both sides of the park assist light.

I recall somewhere in this forum Loren posted an official Porsche image of where devices can be placed on Cayenne windshields -- many Porsche windshields have thermal layering which do in fact interfere with GPS (or radar detectors, etc) ability to pick up a signal. The locations you specify would not work -- but the best bet is to try it and see what your results are. My handheld GPS device can pick-up a GPS signal from the floor of the backseat -- some devices are better than others.

Not the best solution but one I've seen: GPS antenna under the sunroof glass -- but sunroof glass may also be thermal and you have to deal with wires. Up around the rear view mirror is usually clear -- search for that post and picture and you'll be set,

Also, review your option codes and determine if you have all around thermal glass.
