does anyone know if a 03 radio without hud or onstar will work in a 02 with hud and onstar the cars are both gt's the 03 has a equalizer in it and the 02 does not, both are factory radios, i know they dont have killer sound or thumping ability but im old my hearings bad but my killer radio days are behind me, but will still crank up a good classic rock song !!!!
