well, I agree that having it "always on" would be nice. I'm just worried that it might kill my car's battery to have it always ready to recieve transmission. I was also wondering if the car player can recieve data when it's not in "home" mode. I'd like to make sure the Empeg isn't always on, as I'm pretty sure this would draw a fair amount of power as well.

One way to get around this, like you suggested, is to have a WAP and the empeg's 12v power supply wired up to a switch, so I can hit the switch, walk inside, upload songs, and when I'm done I'd have to walk back outside and hit the switch again to turn everything off. I usually start the upload and go to bed, so I would have to turn everything off in the morning. Do you see this as being a problem?
