Car system - BMW

[JackVa1]

Anyone know what is in My 2003 Z-4 BMW? It's sealed up and I wonder what it is. I know i cannot add an mp3 to it because it is tied in with a computer and NAV - just wondering.

Has two subs and 8 other speakers and sounds just OK..

Many Beemers use H/K. Probably some form of JBL or Infinity speakers. Who knows? Most of the Beemers I have seen with H/K, say H/K on the speaker grills. I would imagine they roll off of an assembly line in China with the rest of the crap speakers that come in cars.

Head unit could possibly be built by Blaupunkt.
