[Closed] Tell me about in car DAB radio converter things...

Having been given a DAB radio for Christmas, I am finding lots of new stations.

Planet Rock currently being the favourite.

Also, my van has terrible FM reception due to having to the interference caused by my laptop and smartphone needing to be on charge most of the time.

So, would the DAB reception be affected by the cheap 12v chargers that come with everything? And any recommendations for discreet (i.e glovebox rather than windscreen sucker mount) DAB converters, that I can plug in with a 3.5mm aux lead rather than an FM transmitter.

And does it just share the FM aerial? Being a company vehicle, I'm not allowed to install/modify anything. (unless they don't notice!)
