Installation Steps
1
Mount It
- Wipe your windshield with isopropyl alcohol and let it dry completely
- Warm the mount adhesive briefly with a heat gun or hairdryer — improves bond strength
- Peel the backing and press the mount firmly from the centre outward for 30 seconds minimum
- Leave the mount undisturbed for 24 hours before attaching the detector
Important: Press from the centre only — pressing on the logo side can crack the plastic.
VHB Tape: Wait 24 hours before loading the mount. Full bond strength is reached after 72 hours.

Wire It Up — Choose Your Power Option
RAD MAG ships with one of two power tails depending on what you ordered. Follow the matching option below.
Easiest
Option A — Mirror Tap
Spade-plug tail. Plugs straight into your rear-view mirror's existing power feed.
- Drop the mirror cover to expose the mirror's power loom
- Identify the switched 12V and ground wires (a multimeter helps)
- Slip the spade plugs onto the matching wires — no cutting, no splicing
- Tuck the tail along the headliner and refit the mirror cover
Option B — Fuse Tap (Bare Wire)
12V bare-wire tail. Taps a switched fuse slot for ignition-controlled power.
- Ground: bolt the black ring terminal to any bare-metal chassis bolt
-
Power: connect the red wire to a switched fuse slot via a Fuse Tap
- Insert a 2A fuse into the slot furthest from the tap blade
- Place the original fuse into the remaining slot
- The original fuse must be rated higher than 2A
- Tuck wires along the headliner and down the A-pillar
Not sure which one you have? Mirror Tap ends in two flat metal spade plugs. Fuse Tap ends in a red wire + black ring terminal.

Plug In & Go
- Snap the magnetic connector into the top of the mount
- Plug your radar detector in and clip it onto the mount
- Start the car — your detector powers on with the ignition
Pro tip: Always verify polarity and switched-vs-constant power with a multimeter before connecting. Wiring to a constant 12V source will drain your battery when the car's off.
Need a hand?
Mirror Tap is the cleanest install — no fuses, no splicing. Not comfortable with vehicle wiring? Any local car audio shop can finish either option in under 15 minutes.
