Is the DIN hole cut out up top where the stock radio is?,or is it where the tape player goes, near the steering wheel?I ask this because my brother has an ra40 and i put the head unit where the tape deck went.
if the hole is there, then u have to just do the wiring and mount the new h/unit's locking cradle in there and its done. But u have to unplug the aerial lead from the standard radio (uptop) and get and extention lead (costs like $5..) in order for it to reach the new h/unit.
