ok I love the look of my radio, but it isn't working right.... the frequency tuning knob is broken... luckily i only need one frequency to tune into my Sirius reciever. periodically the FM radio will just not work but the AM will? I have heard there is a kit to rebuild the radio, if not then it looks like it's time to hide a real deck in the glovebox.... but i'd rather not spend the time to do that. any ideas?
