Dukes App

Pair Your Detector

To connect your radar detector to the app, open Bluetooth & Detector settings and tap Scan. Your phone will search for nearby detectors over Bluetooth (a short-range wireless connection). Select your detector from the list once it appears.

Supported detectors: Uniden R4, R4w, R8, R8w, R9, R9w and Valentine One Gen2 (V1G2).

Don’t have a detector? No problem — enable Standalone Mode to use the app without one. You’ll still get police reports, camera alerts, navigation, and everything else.

Set Your Units

Open the map drawer, choose App Settings, then Driving & Modes (or use Ready to Drive → Driving Mode). Pick your preferred units: KM/H (kilometers per hour) or MPH (miles per hour) for speed, and KM or Miles for distance. Every screen in the app will use the units you choose.

Download Police Enforcement Overlays

In App Settings → Map & Display (or Library & tools → Data & Downloads for some packs), download the overlay packages for your region. These paint a heatmap (a colored layer) directly onto your map showing areas where police have historically been reported setting up speed traps — warmer colors like red and orange mean more activity. Packages are available for all of Canada, the United States, Australia, and New Zealand.

Configure Alerts

Under App Settings → Safety → Tones & alert audio, choose on-screen alert size and colors when a detector is connected. “Bands” refer to the different radio frequencies that police radar guns use (like K, Ka, and X) — each can have its own color so you can tell them apart at a glance. Use Visual alerts and Voice alerts in the same Safety section for flashes and speech. For camera warnings, open Road Alerts and make sure Speed Camera Alerts and Red Light Camera Alerts are turned on.

Drive

Keep Screen On enabled, mount your phone where you can see it, and hit the road. The app takes care of the rest: it automatically reconnects to your detector, shows you alerts as they happen, and quietly memorizes locations with harmless signals (like automatic store doors that trigger false alerts) so it stops warning you about them over time.

CarPlay: GPS lockout & JTK

On Apple CarPlay, the right edge of the map shows four stacked buttons: Sound, Radar mute, GPS lockout (shield with lock), and JTK (slash-through lightning bolt for supported laser setups, or Map tools like recenter and zoom otherwise). Full behavior is under App Settings → CarPlay in this guide (sidebar: CarPlay), starting with CarPlay buttons at a glance.
