I just bought a 01 altima with this stereo in it. It wont light up the display when the car is turned on. its on cuz i hear static and it picks up one station. I dont think the antenna is plugged in. I might need an adapter or something i dont know.
could be 3 things, if it has a flip down face the contacts could be shot and need to be filed or cleaned to make a good connection again. the radio will need to be pulled out to check if the anttena is connected still if not just plug it it if u need a adapter u can pick those up at any local bestbuy, circuitcity, or car audio shop. or lastly the radio could be shot.
