I have a Citroen Relay 2016 vintage with DAB radio, but not sat nav. Went out in the van the other, interestingly just after it was three years old, and the DAB just stopped working. Works OK on AM and FM. Now does not want to select the DAB option. Tried all sorts of variations but no luck. Almost seems that after three years and out of warranty the DAB stops. Anyone else experienced this or has a solution?
