Installing a Alpine CHA-S634 in my 2005 325i

[Uncle Rusty]

I discovered that my new E46 has the CD changer bracket and trunk liner already installed in the car. (No navigation, or Sirrius installed) It looks like all I need is the CD changer and electronic interface hardware!

I was about to order:

Alpine 6-Disc MP3 CD Changer CHA-S634
Alpine Ai-Net to M-Bus Adapter KCA-130B
Soundgate Adapter ABMW35V5

While about to place my order, I discovered that some BMWs have a DSP audio system that requires a different Soundgate Adapter (BMWDSP). How can I tell if my audio system has DSP?

The site I was about to purchase from lists the 325i up to 2004, no listing for 2005, so I just wanted to make sure that I order the correct Soundgate Adapter.

Thanks,

Russ

Correction:

Title line should read:

"Installing *AN* Alpine CHA-S634 in my 2005 325i"

Does it say what you have on the window sticker under options?

You don't have DSP in your 3. I think the 5 series does.

The window sticker says "Anti-theft AM/FM stereo/CD audio system" and "Pre-wired for CD changer."

I don't think that it has DSP audio, I just thought it was a good idea to check. The car came with leatherette/wood trim. Before (I think) wood trim came only with leather. Also, it came standard with a glass moonroof, and automatic climate control - all of this on a base model. I just don't want to find out BMW added DSP after ordering a Soundgate Adapter for non-DSP.
