Know your mount

2-Pin vs. 4-Pin - what's the difference?

Every RAD MAG mount snaps on with the same magnets and holds the same way. The only thing that changes is what travels through the pogo pins - pick the connector that matches your wiring.

4 Pins 2 Magnets

4-Pin

Power + Data

Four pogo pins carry power and the remote-mute data signal. A magnet sits either side of the connector.

2 Pins 2 Magnets

2-Pin

Power Only

Two pogo pins deliver power to the detector. A magnet sits either side of the connector. No data line.

0 Pins Your own power

Non-Powered

Bring your own power

No pins - a clean magnetic mount for buyers who run their own power lead straight to the detector.

Which one do I need?

Same snap-on magnets - pick the connector that matches your wiring.

2-Pin

Power only

Best used for Simple, clean hardwiring (mirror taps or basic fuse-box power) where you just want the detector to power on and work as usual.
Confirmed Standard power-only setups.

4-Pin

Power + data

Best used for Required if you're using the manufacturer's factory "smart" hardwire kit with a remote-mute button.
Confirmed Uniden R3 R4 / R7 / R8 / R8NZ / R8W, Escort EZ Mag, V1 Gen 2.
Are 2-Pin and 4-Pin mounts interchangeable?

No — they're completely non-interchangeable. They use different physical connectors and internal layouts. Mixing components or forcing a mismatched connection can permanently damage your radar detector.

Does my detector still fully function on 2-Pin?

Yes. All on-device features - mute, mark, top buttons, display and audio alerts - work perfectly normally on both versions. "No alert out" simply means the 2-Pin mount can't send signals to external dash accessories (like a remote mute button).

What about the Non-Powered mount?

The Non-Powered mount has no pins at all - it's a pure magnetic mount for buyers who already have their own power source running straight to the detector (for example a coiled cord into the lighter socket). Your detector snaps on and off exactly the same way; you just keep using your existing power lead.

Bottom line: Want to run an Escort Smart Cord, Uniden Remote Mute Kit or Valentine One ESP device and you're comfortable soldering wires? Get the 4-Pin. Otherwise the standard 2-Pin is right for most users. Need pinout details? See the full wiring guide - or message us before you buy.
