But the biggest problem is that digital radio is the HD-DVD of in-car audio, destined to be trumped by the Blu-Ray alternatives before long.
So, what are these alternatives?
There are quite a few. The most obvious are the plethora of internet-based streaming services, such as Pandora, Spotify, Google Play Music and Apple Music.
As long as you have a mobile data connection, you can listen to whatever sort of music you choose, with playlists generated from songs you like, via your mobile phone. Some services are supported by ads, but ad-free experiences require a subscription fee.
And, with Apple CarPlay and Android Auto systems fitted to more and more new cars, you might even be able to hear a death knell ringing out the next time you tune in to DAB.
The drawbacks of internet-streaming services are much the same as anything that relies on radio signals of any kind: reception. If you’re not in a mobile service area, Pandora and its ilk become about as useful as a glass hammer, so it can be worth having alternatives if you’re headed off the beaten track, or if you use a telco with spotty service.
Should this be the case, you can always connect your phone or audio player via Bluetooth or USB. Some cars have SD card slots and others have onboard hard drive space for you to store your favourite tracks.
Otherwise, there’s always humble old FM.
