When I was looking at these new last year for the MR2, the Halfords models didn't include a DAB aerial. It's only about a tenner for a Pioneer clone aerial from eBay or Amazon. Sticks onto the windscreen and provides at least as good as signal as the inbuilt one on my Mini. Decided against this in the end as I wanted something with a better quality display, but looks like they've got a few others in stock.
One left in Halfords / Norham Road - Silverlink..can't decide to buy it
It should fit any car with a double din slot.
Any advice on how I would figure out if this fit's my make/model of car?
You can adjust the brightness. Check the manual, (nerd)
