well, being able to use the built in EQ might be a good thing for certain...so. But its also good to know about the Sony AMP sharing device. That might come in handy too since i may have to mount the Empeg in a hidden place, it will be easier to access the switch to decide between CD/Tuner/Empeg.

Thanks all for all your comments...it is really helping. I wish I could get this kind of response from the BMW user group!!!
