I believe the iPod system is only compatible on the 2002-2003 E39's. My mom has a 2000 528iA and i have done a little maintenance on the cooling system, it's very similar to the E34 525i as far as the engine goes. Congrats on the car though. Believe me, we've tried roadly.org
bimmerforums seems to be good for non-technical things. I'd ask here first, as many of us have E34's as well as other model BMW's, then try roadfly. www.bmwtips.com
