My car has DAB+ and it kinda sucks. In principle it's better, the audio quality is better and instead of static it decreases the volume when the signal degrades. But it's so sensitive to interference and when it looses the signal (or thinks it has lost it), it starts hunting and gets totally confused. Often it can't re-acquire the signal till I just hit the button to re-tune to the channel.
Maybe it's just the radio in my car is bad (2016 Chevy, nothing special) or I live in a bit of a dead zone or something.
I imagine if you don't move it would work perfectly, but when driving it's mostly annoying. Which is a shame, because a lot of stations are only on DAB+, not having the money for an FM license.
