2012 Roomster Swing radio upgrade to Amundsen+

Hi all, newbie here so excuse me if I’m going over old ground.

We’ve just got a 2012 Roomster SE with a Swing head unit. The sound quality isn’t the best and I’m looking at getting a DAB unit. Not too bothered about iPhone connectivity but a built in Sat Nav would be handy.

Looking at various posts I know I’ll need a DAB aerial so either a stick on or if I’m feeling brave remove the headlining and swap the roof mount one and a GPS receiver behind that top glovebox for navigation.

I’ve seen SK RNS 315 3T0 035 192 C or M which look to have the blue DAB input connection.

Has anyone done the same in a Roomster and could offer advice?

Thanks,

Carl
