So we managed to get the radio on by disconnecting the car battery for 40 mins and reconnecting it.
Next problem... Now the radio is on, we can't switch modes! For example, we are stuck on AM, toggling between LW, LWA, MW, MWA. But we can't get to FM, AUX or anything else. If we put a CD in it will switch to that and start playing, but we can't change tracks or anything.
