How to Solve DAB Radio Interference from Dash Cams

What causes DAB radio interference?

DAB interference occurs when electrical noise disrupts the radio signal. All electronic products emit some electromagnetic noise — even mobile phones — and LED lights are one of the most common sources of DAB issues.

Do Dash Cams cause interference?

Miofive Dash Cams are designed with optimized circuitry to minimize electromagnetic emissions. In normal use, they generate very little interference. However, because vehicles differ in their antenna design and wiring layout, some models may be more sensitive to external electronic devices.

Why am I experiencing problems with my DAB?

DAB systems vary widely in their susceptibility to interference caused by external emissions.  If you Google search the make and model of your vehicle followed by the words "DAB interference", you may find other people are experiencing similar issues with their vehicle when using other products and might be able to offer a solution, which is specific to your vehicle.

What to do if you experience DAB interference?

In the unlikely event that you notice reduced DAB reception after installing a Miofive Dash Cam, here are a few steps that may help:

1. Re-route the Power Cable

Run your dash cam’s power cable along a different path — ideally on the opposite side of the car from the DAB antenna wiring. Even moving the cable a few inches away from the roof lining or antenna harness can help.

2. Add Ferrite Noise Suppressors

Clip ferrite noise suppressors onto the power cable, as close to the camera and hardwire kit as possible. These block high-frequency interference and are a simple, cost-effective fix.

3. Aluminium Foil Shielding

In most reported cases, interference comes from the rear camera or its extension cable being too close to the DAB antenna. As a quick test, wrap the rear camera module or its cable in a couple of layers of aluminium foil (leave the lens area clear). This can help block stray electromagnetic emissions and often restores DAB reception during testing.

4. Contact Your Vehicle Manufacturer

If the issue persists, consult your vehicle manufacturer. Some cars are known to have DAB interference sensitivities, and they may be able to recommend a specific fix.

Key Takeaway

Most Miofive users never experience DAB radio interference. In the rare cases it does occur, it is usually related to cable routing or vehicle sensitivity rather than the dash cam itself. By re-routing cables or adding ferrite suppressors, you can often restore clear DAB reception.

At Miofive, we remain committed to providing high-quality dash cams that deliver clear evidence, safe driving support, and peace of mind — without compromise.
