You have to download the app or use it in highway radar(best app ever)

most of the alarms are doors and mazdas. you can edit to auto silence the GPS location and the specific bandwidth of the mazda

Optimization and quick research are required with a purchase like this. Great support forums out there and YouTube videos.

I have had my R3 and R7 for several years now, and they have been effective in creating more situational awareness. I do not own these because I speed. Instead, they help me avoid unnecessary interactions with the police. Driving is complex, and sometimes you need to speed up to overtake or avoid situations altogether. Or the opposite is true, driving conditions change, and speed limits drop. These bring back my focus during long drives and help me make decisions and adjust behavior as necessary.

Agreed, just need to optimize it. Moving to R4 so I can add bluetooth and "not speed" while riding.

How do you find out the bandwidth of Mazdas?
