A bluetooth OBD-2 plug. Allows you to connect to a Palm, PocketPC or WinXP laptop (or MAC) wirelessly and read/clear codes. I got one and it's great to read the graphs on my PocketPC coming right out of the port.

I also found some open source software to use with it (or any other connector to the OBD-2 port): http://www.qcontinuum.org/obdgauge/

Very intresting. I have a ScanGauge now, but it's really bulky. I'll look into this when I get home. Thanks

BTW, I have the software for the Kenwood but nothing to burn it with. Mail it to you and you'll mail it back?

Now that is cool. I have a windshield mount for my PocketPC (so that I can read my GPS maps) and you could monitor your ECU in real-time on the road.
