This may sound stupid, but where is the antenna for the 93 318i. The car has had a complete front-end replacement for the M3 design. The radio does not work due to the antenna not being hooked up. Was not sure if the antenna housing was shaved off with the rest of the body effects, or if it was in a window. I am new with BMW's as you can tell. If it was shaved off then I will run it so it keeps the smooth look, but if this car never had a antenna mounted like the domestic cars(on front fenders, or trunk), i will run it according to the manufacture design. Thank you again.
