p38 stereo question

hi guys havent been on for a while, had a few months of trouble free motoring and swamped down at work!!

just got a quick question regarding the standard stereo, ive read alot on here about people having the diversity head unit, and im afraid ive got the poor mans version and is only the Program head unit, it hasnt got any visible controls for a cd changer but does anyone know if this head unit can take one, havent taken it out yet to have a look at the back( being a lazy sod and asking you guys first!!!!) I dont want to get rid of the head unit as i really like the quality of the sound and the ease to use the head unit.

thanks for any help.

the sound in mine is fine and i got an after market unit!!! the sound is to do with the door amps not really the stereo. any decent unit will give you good results!
