Im having trouble with my DAB radio not picking up any channels and the screen is stuck on searching, signal here not a problem as my other vehicles are okay. Code reader states fault with L-band antenna. Ive gone to change the shark fin Ariel but noticed there is a difference on the Ariel lead plug as one is coloured pink (original on my car) yet the new one has a blue connector and both units have the same part number, does anyone know the difference between the two please? Car is XKR 2011 with DAB and sat nav, cheers.
