A Pop doesn't have an aux port as standard, you can buy a aux lead that plugs into the back of the standard Panda radio but what I did when I had an DAB adapter before changing the headunit was I had a Nextbase DAB adapter which worked on the FM frequency, I just had mine set to 87.5 on both the radio & the adapter as there's never usually any stations near that frequency & it worked pretty much perfectly anywhere in the country
