I got an adaptor from Amazon, about £35, it’s bluefree I think, but there’s loads that are identical when you search for car dab adaptor.
Anyway reception is pretty good, I live in the countryside so limited choice, but I can get radio 6, and when I go down the motorway picks up all the others. Dead easy to fit as well. Only slight annoyance is a faint high pitched noise , more noticeable when theres just chatting on the radio rather than music, and not noticeable at all when I’m going down the motorway with road noise and the music turned up.
