PCM related question

[svetlaev]

Hi everyone,

I have recently purchased a navigation unit (still waiting for it to be delivered) but started doing some research. My S (08/04) originally came with CD player (CD-24 I assume) and cd changer with BOSE sound. So I had a couple of questions:

- First of all would I need any additional hardware to install the PCM?

- The second question is that how can I figure out is it DVD or CD based? as well as it's version? All I know about the unit is:

"PCM2 E1 USA EC: 124"

"Model No.: BE 6636"

"Serial No.: 45032739"

"Accession No.: 0331621"

"Date of manufacture 08/04"

"7L5.035.191G"

"ZSB 7L5.919.886G"

- The third question is do I need to buy GPS antenna?

- And the final question would my CD changer still work?

Thanks in advance =)
