Hello new to the group have a 2017 tipo 2nd hand working fine today when dab cut out and displays (see pic) Station unavailable, tried changing stations works for a few seconds then get same message. Tried resetting now rescanning does not find any stations except the one on the pic. Could it be ariel, everything else works fine USB phone am/fm apps. If ariel how do you take it apart to check or best to take to a dealer? Please advise many thanks.
