FitDVR Power Adapter 3‑Pin for BMW & MINI Dash Cams

FitDVR Power Adapter D3-024 is a plug-and-play 3‑pin dash cam power supply for BMW and MINI F/G chassis that delivers both 5V USB and 12V DC outputs with an LED display.

This compact harness converts your vehicle’s 12V mirror bracket connection into stable, dedicated power for dash cams, radar detectors, and USB devices without cutting factory wiring. It is designed specifically for BMW and MINI models that use a 3‑pin connector on the rearview mirror bracket, and it keeps the rain sensor and vehicle warranty intact while providing real-time voltage information on an integrated LED screen.

Will this adapter fit my BMW or MINI model?

FitDVR D3-024 is made for BMW and MINI vehicles that use an F‑Chassis or G‑Chassis mirror bracket equipped with a 3‑pin connector. Before ordering, visually confirm the mirror bracket connector has three pins — the adapter will not match other connector types.

• Compatible: BMW and MINI F & G chassis models with 3‑pin mirror bracket.
• Not compatible: vehicles with different mirror connectors or aftermarket mirror wiring.
• Quick check: inspect the back of the mirror bracket for a 3‑pin plug before purchase.

How does the D3-024 supply power to my dash cam and accessories?

The unit accepts the car’s 12V input and provides two separate outputs: 12V via DC cables for dash cams/radar and 5V via USB for devices that require USB power. It includes multiple cable tips so you can connect different dash cam manufacturers without extra adapters.

• Outputs: 12V DC (3.5mm cables, RJ11) and 5V USB (Micro, USB‑C, Mini USB).
• Input: standard 12V vehicle power from mirror bracket.
• Included cables: six common output leads for wide device compatibility.

What makes the FitDVR adapter easy to install and safe for the car?

The harness uses a dedicated plug that mates with the factory connector so no splicing or permanent modifications are required. Installation is plug‑and‑play, preserves factory systems such as the rain sensor, and is designed not to void manufacturer warranties when fitted correctly.

• Installation: special wiring harness, no cutting or soldering.
• Vehicle systems: does not interfere with rain sensor or mirror functions.
• Warranty: designed to avoid voiding factory warranty if properly installed.

Why is the LED display helpful on the D3-024?

The built‑in LED shows real‑time voltage and current readings so you can confirm the adapter and your devices are receiving proper power. That visibility helps diagnose voltage drops or cable issues without guessing.

• Displays: current and voltage for quick troubleshooting.
• Benefit: ensures reliable power delivery for dash cams and sensors.
• Convenience: visual feedback during installation and daily use.

Who is this for: The FitDVR D3‑024 power adapter is aimed at BMW and MINI owners who want a clean, OEM‑style power solution for dash cams, radar detectors, or USB devices. It suits DIY installers and professional fitters who need a reliable, multi‑output harness with an LED readout and multiple connector tips to support a variety of dash cam brands.
