i just bought this car today and for some reason the radio and the on board display all light up but there is no letters or numbers for either one and i dont get any sound from my speakers. fuses are all good. the car is all bone stock. im wanting to keep the original radio in the car if possible just thought id see if anyone knew something that i didnt. im wanting to tear into the dash and look around... i just dont know what to look for i guess any help would be great thanks
