DAB is now standard on some BMWs since Jan 2013. Which car are you looking at?
Might be an idea to get it anyway. Isn't AM/MW/FM being turned off in the next couple of years??
If you listen to Radio 5 it's great, I've had it for a couple of years and wouldn't go back now. Had very few reception problems with it in the XF
I experience few DAB reception problems here in Oxfordshire & that's with an aftermarket Sony in an old Alfa!![]()
Hasn't the analogue TV switch-off meant that the signal could be boosted a few Db for DAB?. When I first got DAB it used to cut out going under bridges etc, but it rarely happens now.
