Not had any issues on my Golf with a Nextbase.

Also be certain it is not powered on when the car is shut down or you may return to a flat 12v battery.

 

I have one plugged into the 12v and it's been fine. Granted I tend to listen to something streaming but when I do have dab on it's fine.

 

Using Nextbase 380GWX where rear camera wiring in close proximity to antenna in rear window without DAB issues.

 

I’ve got this one - front and rear camera. I listen to DAB all the time with no issues.

Fitted a Nextbase to my Skoda Octavia and it killed the DAB reception on a Pure adapter.

I narrowed it down to the 12V USB adapter. I found an Anker adapter, with a metal casing that solved the problem.

 

Thank you all for the feedback.

Can those who've done it suggest a fuse to use for the piggyback? I imagine that the choice of circuit can be a factor in minimising potential interference and if you've had success then I'd like to benefit from your experience.

I'd like one that's switched. Although the camera claims to ensure that it won't fully drain the battery, I'm not comfortable in believing it - I'd rather the power went off with the ignition.

Thanks again.
