What are you connecting the emulator to? You going to use a pc with winamp or did you get a yampp3 ?
I was originally going to put a small mini-itx motherboard into the car, but when I actually got around to it I had all kinds of logistical problems so I ended up ordering a kit for building the yampp3 - Waiting for it to arrive
I`m going to use it to connect to a laptop, have built a 4.5A 15V powersupply for it and some nice touch screen for Navigation Purposes
