ihave 2002 2.5 crd grand voyager.radio has stopped tuning in apart from only 2 stations .before it was brill almost every channel.antenna in side glass seems fine and amp been tested and fine.
any suggestions out there ?

 

clean the window.

 

Most likely your FM tuning module or AGC unit has failed. Try tuning into an LW/MW/AM channel, if this works then most definitely the FM portion. If not the whole radio may well be shot.
