radio or no radio

just checking the wireless on the van . on handover i didn't bother much about music or news other than seeing the channels skip. this morning tried to preset channels. the thing changed lots of stations but no sound. thought it must be me but after much head scratching and blaspheming i gave up and off to the dealer. two hours of dashboard removal found the problem. not connected to the aerial. slight slippage on AS quality control. funny how its just accepted as normal today. no big deal. happy days.
