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?
