1995 BMW 318i Stock CD changer Question?

[SammyD]

Hi, I'm in the process of purchasing a'95 318i. Does the stock deck have cd-changer controls and if so how much is the stock cd-changer? I used to have an Acura Legend and the stock changer had the Acura symbol on it but was really an Alpine chm-s610 changer so I was able to purchase the changer from an audio store rather then pay big money from the dealer. I'm figuring it's the same with BMW and would like to know what brand and model # it is. Also where is the stock changer connection?

Thanks
