Hi Guys, I have a Skoda Karoq sportline TDI 4x4 on a 69 plate.   Around a year ago I got Halfords to hardwire in a Nextbase 522GW front and rear dash camera set up  (Separate rear camera is on rear boot window).  There is definitely an interference problem that I can make occur by simply unplugging the camera and returning the cabling and I can lose or gain DAB stations whilst stationary.   The DAB radio has been checked by Skoda and is fully up to date with latest firmware etc and thought to be good.

 

I've read various posts on the internet internationally and these are well known problems with many cars, but I just wanted to know if any Briskoda members had actually managed to resolve the problem on a Karoq?  If so how did you do it?

 

Was it  a matter or re-routing the cabling?

Did you shield the cabling, if so what with and where?

Was it just the rear camera causing the issues?

Did you put ferrite anti-interference clips on?   if so, what size, how many and where?

Did you get to a stage of saying stuff it and remove the camera system or change brands/makes of camera?

Did you change how or where you tapped into the ignition live?  

 

I'd like to get this sorted today if at all possible and any help or advice would be much appreciated, even if that's a conclusion of saying that all dash cams and all setups are just as bad and give similar issues!......

 

cheers

Hi AndyGrob73,

    I have a nextbase 322GW dashcam and have the rear cam window mounted version.  I wired it myself and routed the cable for the rear  under the trim on the floor just below the offside doors.    I have radio 2 on DAB and get no interference.   Apart from dropouts on the local BBC radio station there is no interference.

My car is the Karoq 1.6TDi SE and has the Bolero radio.

  My dashcam is not hardwired in.  I use the 12v socket via a switch.

Maybe the interference is caused by the cable routed too close to the aerial feed.

Hope this helps

I think I've sorted it now, and it seems to relate to rear camera positioning.

Originally it was located top middle of the windscreen and within the first electric core of the heated rear window seated on glass.  I've now located it off the glass, on the plastic cowling of the rear window at the near side.  I've also put a ferrite interference suppression block over the mini jack connector to the rear camera, and tucked it behind the plastic cowling of the rear tailgate window.  So far so good, but will report back in a week or two after it has had a run around the local North Yorkshire roads.  Previously it had been really intermittent reception up and down the whole country to the point of annoyance and not using the radio at all.

 

Dragging something up from my distant past memory. Is this something that a ground loop isolator would help with?

 

It used to be a common problem with wired intercoms on motorbikes getting interference from the engine. Could the camera be interfering with the radio?

 

I'm a numpty re electronics and this came into my head as a electronic interference solution I used in the 1990s albeit for a different problem.

Guys, had a good run out over the North Yorkshire moors and back, and the DAB radio was faultless. 

 

I think that the key to resolving the problem has been moving the rear camera away from the wiring within the glass for the heated rear window.   Hope that this helps others too.

Hi Andy,

I had the same issue as you so fitted a clamp on ferrite filter around the cable immediately after the micro-usb connector going into my old A118c dashcam I repurposed from an old car. The filter made a big difference but when you get away from the bright lights of Hull on a back road the FM reception gets wiped out until you power off the dashcam.

Do you loop the cable twice through the filter and can you post  pic of where you have the camera fitted please ?

Are you using 3M double sided stickies to mount to the plastic or a clip of some kind as my dashcam falls off when the car gets warm in sunshine.

 

Appreciate any advice.

Hi Andy, I'm having the same problem you had and just found your post. Did you provide an answer/pictures about where you relocated the rear camera and what you used to fix it in place? If not could you help and post pictures.

 

Thanks

Take a look at this!
