Question on CD changer install

[kilo]

Howdy folks, me again. Found a slightly used (2 months) BMW 6 cd changer that I want to put in my 330i. My car has no nav in it, but does have the door and storage area on the left side of the trunk. This CD was mounted under the rear deck of the 3 series it came out of. My question is, can I just buy the install kit from the dealer (about $50) and have all the parts I need, or are they already all there behind that panel? Any input is appreciated. Hope you all had a good time Sunday. Was going to go, but had an in-law thing I couldn't avoid. Maybe next time.

Just wanted to let everyone know that the changer went in fine. Just so you all know, on the new 330i without the nav system, the car comes with the trunk liner already installed (the door is there and there are 2 shelves behind it). Also, once you take the trunk liner out, the mounting brackets are already in place. All I needed to get were the 2 brackets that mount on the sides of the changer itself that secure it into the bracket. Works like a champ.

Kilo, Thanks for the info! I'll be purchasing and installing the CD-Changer as well and was wondering if I needed to buy all the brackets. Now I know that I just need to the two side brackets.
