Probably but if you aren't in a great reception zone it is annoying, when it auto selects from fm to dab the volume changes so it is actually more annoying than leaving it on fm
I've had my custom 2 years and have it on fm.
I'm in North Wales though.
To answer your question though it should be a simple question of fitting the dab radio and antenna then turning it on in ids configuration.
Depending on what you have now. And cost.
