Has anyone successfully integrated one of these in to a car PC? It is supposed to be plug and play under XP, but I couldn't get it to work at all unless the volume was turned completely off (yes, off). It does work fairly well under Vista but when I turn the volume down via Windows or Streetdeck it doesn't turn down all the channels so my subs volume has to be controlled manually.

ESI apparently has no support network, no forums, nothing. Their website says to contact your local distributer... Yeah, like they will have access to information I don't. The manual isn't a lot of help either. It is mostly information on how to set it up with music apps, which is a little strange since it doesn't even have any inputs but I digress.
