corsa 2000v mw radio reception

Hi there

when the engine is off, the reception of the radio on mw is perfect (as
is fm)
but as soon as i start the car, the mw reception gets a lot worse, like
there is interferenece, fm is perfect though

any idea what the problem could be?

thank you

 

Whats mw?

Probably fine the co ax is loose at the aerial base - just lower the
headlining slightly and check the connection at the base - it is the one
covered in foam so you will need to pull the foam off.
