Sony CDX-GT610U Ducato

[dgg]

I have a Sony CDX-GT610U Radio/CD play in my Ducato campervan (first registered June 2009) and I would like to have the unit continue playing when the vehicle ignition key is removed. Is this possible? thanks dgg

just a case of swapping the ignition live feed for a constant feed on the ISO block
