Pretty sure I read that someone here had integrated their detector with their factory heads up display but I forgot to save a link to their post. It was also a pricy custom installed option but having the directional indicators in the HUD would be the gold standard.

 

In aviation we check our windshield heat using the magnetic compass. The heating element current will cause an immediate 10-20° compass swing.

I’m guessing the same thing will happen with your Cayenne’s windshield. You probably have a compass in your phone or perhaps a sports watch. The vehicle compass may have a compensator and might not show the change.

 

What do/did you fly?

Most suction cup radar mounts are above the radar unit making it difficult to get high enough in the cutout for the best signal. Here’s a pic of one I made up using an under mount with the detector held on by heavy duty Velcro. Radar units have vents so this might not work for units with bottom vents. This is my Uniden R7 with a mount purchased on Amazon mounted in a Mercedes.

 

PM sent. No need to bore everyone. 😀

 

This is specifically why I avoided both the heated windshield and the thermal and noise insulated windshield in my E-hybrid Coupe spec. Even if you line up a radar detector with the opening in the windshield, it will be blocked from receiving signals from behind of the sides. Also, you use up space for a toll tag.

 

How did you supply the power? Did you use a mirror tap? If so, where exactly did you tap into for the power?
