My wife is not impressed with the DAB reception in our new Kodiaq. Having driven it, I agree.

When we ordered our car, we decided to get the garage to install a new Nextgear522 dashcam before we collected it. The cam is mounted next to the rear view mirror.

I have read that dashcams can interfere with DAB reception. Therefore, I tuned to a DAB station which we cannot quite get. As soon as I disconnected, removed power, to the dash cam, reception improved. In fact it was perfect. Reception disappeared when I powered up the dash cam.

Is this a known problem?

Any suggestions as to how I can improve things?

The nextbase 522 has an 3.7v internal battery , if you unplug the power lead from the base then turn it on again. See if it still interferes with the dab.

If it doesn't you could try an alternate route for the power cable.

If the installer didn't use the official nextbase hardwire kit, it possibly doesn't have the ferrite core magnet on the cable.

FWIW my Nextbase Duo attaches to the USB-C port next to the mirror with a short USB C/Mini cable and no DAB reception issue at all. A ferrite core cable should help. I'll never drive a car without a dashcam again, since I've had 9 dangerous tailgaters prosecuted ;-)

Thank you for the help and feedback. I am surprised that the kit didn't come with the ferrite core but anyhow, new ones ordered and hopefully that will ease the problem.

As above, I agree the routing of the power cable is the problem.

does the cam not come with a USB port of any kind for the power?

I bought the Nextbase ferrite bead and it didn't work. Initially.

Firstly I don't know how the dashcam is wired or where the power supply cable is. So with that caveat, I'll recount what I did to improve things significantly. I had to clamp the bead around the cable going into the rear view camera. Since the diameter of the cable was less than the diameter of the bead, I inserted a short piece of garden cane alongside the cable to fill the void and tightly clamped the bead around the cable. That worked!

My next post might be to say it has suddenly stopped working but so far I have an awful lot of DAB stations including Xmasfm or something like that. Jeepers.

So tight ferrite bead has satisfied my other half.
