OK, that's what I had suspected. So, to summarize:
  • Some people think that HK equals DSP.
  • Others think that there is no DSP available for E46's (3-series).
  • We all agreed that HK equals speaker button, unless it is a convertible.
  • And from all I found, I would second that DSP means you have a different wir
    ing harness, one that includes optical fiber.

We'll get it together! I just wanted to add that if I select my options on Crutchfield, in example, (2002, E46, 330cic, HK) it automatically selects "Business CD with HK and DSP" - so if there is no DSP on all E46, that would be definitely wrong. I found quite a bit of posts on this forum that mention DSP, so I am a bit hesitant to follow the "no DSP on any 3 series" line.
