| This particular unit comes in chrome or check our other listing for the black version. The masts are replaceable externally on these units and we usually carry the replacement masts in stock. The auto electric antenna is triggered by the blue remote lead on your aftermarket CD or cassette player. These antennas are temporarily out of stock but we do have some on order. We should have them in stock again by 03/10/11. Last update 01/11 |
