Check out my ebay auction for this incredibly powerful and versatile in-car-computer, which includes EVERYTHING needed for the ultimate "head unit". This component features a 160 GB hard drive for huge music and/or full length movie storage (18,000+ mp3's). Also includes DVD-player/CD-Burner combo drive, operating system, GPS with guided navigation and more. Another great option, but not included, is Hondata or a similar tuning and/or datalogging program. Anyway, check it out:

If you could use it for ecu plug and play tuning it might not be so bad
