Poor DAB reception...

[dohboy78]

Not used the stereo much on my Superb Sportline... but when using DAB the reception is turd in built up areas... is this normal?? Any ways to boost the signal strength??

My DAB reception was pants in places and it turned out to be a poor USB adaptor killing the signal completely in poor signal areas.

 USB adaptor? How did you resolve it?

No problem with DAB even with the dashcam fitted which others have reported have created an issue.

Just chucked it away, I now charge a powerbank using the slow car USB and use that to fast charge my phone, no point in trying a new USB plug as it might interfere just as badly.

That's a really good shout, I have a similar issue with my vRS Octy 3, didn't consider taking the USB charger out of the ciggie lighter.

I see. I don't currently have anything plugged in to USB...

Just the USB adaptor plugged into the socket was enough it didn't need to be charging anything, might have just been the display LED causing it rather than the charging part.

USB 12V to 5V adapters are famous for causing DAB interference: I had to try several on my previous car until I found a good one. Not an issue if DAB signal is strong, but slightly weaker signal - DAB is killed completely

 

Hard-wired dashcam eg Nextbase, does not seem to cause any DAB issues - might be that the Nextbase adapter is better designed

I have none of the above... No USB devices or cables and no camera. Always thought DAB was meant to be strong signal wise.

That's interesting.  I have problems with DAB signal disappearing.  I also have have a 3-way cigar lighter adapter with a 5v USB outlet.

 

I have Nextbase cameras front & rear.  At one time, I had a cheapo camera on the back, but it caused terrible interference with FM radio.

(yes I know its an old thread but......)

Something Ive noticed with my Superb is that both with DM & DAB the signal drops out much sooner than it did on my old Ceed.

I have the same USB adaptor I had in that and need to fit the Nextbase dashcam, but thats to come.

I was wondering if I could try using something like this (for DAB reception) in the windscreen (I dont have the heated option) as I used in an L200 previously



Question is which of these connectors on the back is for the DAB aerial (image "borrowed" from a fleabay listing for a 2018 head unit).
My suspicion is its either the pink or yellow FAKRA style connector
