Different broadcast services can behave differently with coverage and equipment. DAB dropout on one route is not the same complaint as persistent loss everywhere.
Record location and equipment changes
Note whether the problem affects all stations, began after an accessory installation or occurs only with a particular device powered. Compare ordinary use safely without changing settings while driving.
If reception is consistently worse than before, provide the timeline and installation details. The workshop may need to assess the aerial path, interference or equipment condition. Do not replace the entire head unit solely because FM still works; that comparison narrows the function but does not identify the defective component.
