I got my R7 about 2 weeks ago updated firmware and ran in my Audi with no issues. Last week I did a hard wire install in my Macan and on Christmas day I drove by a police station and noticed my KA did not go off until after I drove bye and my rear antenna alerted. I live close to an other police station and noticed the same thing a few times. This AM I drove bye a stationary speed sign and the same issue on K band. no alert until I get close to source and the rear alert goes off as I drive past the rear lights up hard with good detection range. Later in the afternoon I se to cruisers parked side by side. No alert from the front. When Im about 50 feet away the rear KA alert goes off and then signal gets stronger as I drive past. I turned around to see if the front would alert in the other direction. Nothing until Im 50 feet away and the rear signal goes off and alerts continue from the rear for a while. I have been able to replicate this with a stationary detector near my house. I did a factory reset and same issue. Do you think there is a problem with the front antenna?

Can you try running it in your Audi and seeing if you have the same behavior? Some vehicles have athermic windshields with a small area for toll transponders/RDs to be able to see signals. Not certain if the Macan has this or not. Just trying to rule this out.

I did try moving the location on the windshield and had the same result. I will try in the other car. I was thinking of trying to go back to old firmware and see if that changes anything.

How close can you get to the LEO Station? Good way to test us find a park LEO who left Ka on and drive as close as you can to it. Some LEO stations have public roads to them that you can drive close
Enough to. Just a thought

I can drive right up to the station or a known Rdf signal the detector doesn’t alert to the front but will alert to the side or rear.

Strange. In order for the side arrows to function the front antenna would have to be working.

I had a similar issue with my first R7. After a couple days I realized the front antenna wasn't working. I purchased it at Best Buy and exchanged it for another new one. This was the first month they were available. My R7 has been amazing since and I'm very happy with it.

So I have been testing all day. It looks like something in the windshield is blocking the signal. I tried in a different car and worked fine. Then I put it back in the Macan and it didn’t work. I opened the roof and held it out and it alerted immediately. Anyone ever hear of that? It is a normal windshield. I’m going to call Uniden Monday.

Your windscreen likely has a very thin invisible film of metal to reflect outside heat. This is Installed in higher end vehicles. I had exactly the same symptoms in my M5 which has a thermic widescreen as well. There will likely be a non metal coated area around the mirror, you can probably visually work out where it is from the outside.

I took a look and cant find an obvious spot. I have seen others mount under the rearview mirror, so I held the RD there and it still did not alert.

Have you ever heard of a windshield blocking RDF? I have an R7 that wont alert with the front antenna. It works perfect with the rear after I pass the RDF source. I have trouble shot and it works perfect if I open the roof and hold the R7 out the top. It seems something in the frond windshield is blocking the signals.

Do you have a heated windshield or metallic tint

I have a 2017 Porsche Macan S with R7 with a hard wired mount. It appears the front windshield is stopping the front antenna on it from receiving signals. . It works perfect with the rear alert after I pass the RDF source. It also works perfect if I open the roof and hold the R7 out the top. I have trouble shot in multiple vehicles, and it only does this in the Macan. It seems something in the front windshield is blocking the signals.

I do not believe I have either of those. Nothing on the build sheet says a heated windshield and no tint that I can see.

There are some vehicles that have athermic glass (solar heat reducing glass) which has a small layer of metallic material sandwiched in the layers. if your car has that it will block radar signals like a Faraday cage... some of the vehciles with this have a samll area near the rear view mirror that is no shielded to allow things like RD's and toll transponders to work, so try near the rear view mirror. if not you will need to get a remote radar detector to have proper performance

I believe heated and athermic windshield can cause this issue with detectors. You might have to do a custom installed detector system or get another windshield installed without whatever is blocking the signal.

Google search or look in manual for allowing devices like GPS on windshield.
There is usually a location designed for this use.
Unless new Porsche insists you use all their built in devices.

I need to look at it in sunlight. I did test the RD in a few spots around the rearview mirror without any additional performance. I would love a custom install but for the price of those I will just stick with Waze and take my chances. Thanks for the help.

I had a similar issue. When I got mine the rear antenna was dead. They ended up replacing it and now everything is fine. If you get it replaced be sure it's with a new one, not some refurb because they tried that with me. Had to replace it twice.

Metallic film embedded in the windshield. There is usually a dotted area near the rear view mirror to allow signals to pass through (this is where they recommend toll pass devices be mounted)
