Where to find a selection site?
 

I'm looking to replace my Audi Symphony system in my 2002 A4. I have specific requirements. 5.1 sound, voice recognition for all attached devices, nav, in-home routing for nav, full iPod integration (including tagging), BT for phone (including voice recon). Auto leveling between sources would be great too.

I am trying to find a site that will let me search for products based on features like those above, to help narrow my decision. As it is I'm going from vendor site to vendor site (with varying degrees of success, Kenwood's site sucks for example).

Can you suggest a good site for this type of data mining?

WTF advice is that? I don't want to replace my car...

How do I report idiot spammers?
