I use DAB in a wide variety of cars, when the model has it fitted, and the only car I’ve had really poor reception in was a Mercedes! There are occasional places that lose signal, but over a 200+ mile drive from Helston or the far south of Cornwall back to North Wilts I usually get a clean reception all the way, with just an occasional drop out for a few seconds, or maybe a minute or two at most. The Merc was shockingly bad, though, but pretty much every car I’ve driven which only has FM has been far worse, there have been a couple of occasions where there’s been no USB phone input, so no music from what I’ve put on the phone and the radio has been so poor I’ve driven for two hours in silence. These are cars that are two to three years old at most.
And phone data is too poor in the south-west to even think about streaming radio, thirty minutes driving with zero phone signal, let alone 3 or 4G puts paid to that. The team Galaxy has DAB, and is in use from 6am to 6-7pm, and I’ve rarely heard that drop out and that’s everywhere from Cornwall across to London and up to Manchester and Liverpool, South Wales and across into Lincolnshire.
Pity our team leader insists on having Radio One on all the sodding time… 😐
