The Infill E3 is probably not a good CarPC platform for the software out there. It's ARM based, flash memory, and ideal more for an embedded solution.

I'm actually pondering selling my Infill G4 at this point. No specific reason due to the hardware, but more to possibly look at some other system that would suit my car better. The Infill G4 is good if you are willing to let the onboard amp drive the speakers. But for me, I need an external or line out solution due to my built in subwoofers that came with the car. the Infill G4 + an external sound card just hasn't been all that reliable for radio use, and it's hurting the install a bit with having to dedicate a USB port to a sound card.

Not sure when I will pull it out, but let me know if your interested in buying it and I'll try to find out what a fair price is for it, especially considering your loss of the empeg.
