Locally for me, DAB reception is acceptable, but not in other parts of the country, particularly for commercial stations.
My UX has front/rear dash cams, as did my previous car ( Corolla, which had much better reception).
In a previous thread on here, ferrite rings were mentioned. I found one in the dash cam box left in the car by the Lexus dealer.
Easy to unclip the top rear door panel and attach to the dash cam wire.
Having said this, I have yet to travel further afield to ascertain whether there'll be any improvement.
