I've just a front and rear Dash cam installed by Halfords and they advised me that the rear camera can cause radio interference. My guess is that it's the location of the wiring going past that from the rear-screen antenna, rather than some kind of RF interference given off by the camera itself.

At the time of install, all seemed fine and FM is... but DAB is not. It works but is no way near as strong as it was. I've read about adding ferrite cores to both ends of the cable and I've done that but... still the same.

I'm going to arrange to take it back but I was told they'd done what they could to minimise it so I'm not sure where I'll stand. Does anybody have any experience of this and/or any suggestions?

Similar problem with my Kuga and Puma when fitting rear camera. I was trying the Nextbase one. It appeared as soon as the cable went near the modules in the tail gate. I even went as far as wrapping the cable with shielding.....didn't work. I've also had issues with cheap noisy usb adapters screwing DAB signal.

Answer.....no rear cam

I’ve fitted a BlackVue DR900s 2ch to my Puma (since new) and not had any issues…

I've got a Thinkware Q800 Pro – the marketing material mentions the rear camera cable has ferrite cores and is shielded to prevent DAB interference.

My DAB works great.

I think mine desensitizes as opposed to wipe the signal completely so depends on your DAB strength initially

Odd. Like Steve, I have the Nextbase and it's effected the DAB signal (not totally, but I loose the signal a lot more than I did before).

I just wanted to post here again as I've solved the issue and wanted to share it. I've written up what I've done - with pictures - on my site. I hope it's okay to share the link...

Nice piece there David.
Thinking of getting the Nextbase 622GW fitted, so I'll keep that in mind if it gets done (time permitting :( )..
Be interesting to see if it cures others with the same problem.

I have a blackvue front and rear cam but haven’t had any issues with dab reception, maybe it’s just with nextbase
