Multi changer CD unit thingy

Right my girlfriend recently brought a renault clio 1.2 16v 51 plate...


...dodges bricks...

Anyway it come with a 6 CD changer box, which was in the boot with one single wire going from the boot to the front of the car, which had a radio cassette player in. It wasn't connected becausde the previous owner took out the CD Player (or better standard radio thing as my girlfriend tried to explain it).

She doesn't want it and has given it to me. I was wondering will the standard fait punto radio cassette thing be capable? Someone told me it will because it has a source button.

the cd changer looks this

I hope thats enough detail. Would someone know how much this would cost me to get fitted by experts because im going tommorrow and don't want to get rid off/told it won't work with my radio! so i fast response would be nice!!

Thank you
