yes, after my factory fitted radio died, i bought a kenwood of a mate and i had to buy a converter from halfords for the connector at the back. but the p38 rangie connector is an ISO type, so lots of makes of cd/radios will fit without a converter, i just managed to find one of the few that needed one!
i currently have a blaunkpukt which doesnt need a converter, just unplug the old radio, and stuck in the new. easy.
