Don’t forget to unplug It once you kill the engine! The OBD port does not provide a switched power lead. So anything plugged into it will draw power all the time. This can only lead to a dead battery : (
Just clicked on the link above, that is the exact unit I bought one week ago! I like it a lot. I have yet to formally wire it in so that the wire is as hidden as possible. I also bought the necessary adaptors so that I can hook power up to switched power. That way the heads up display only gets power when the engine is running. For now I have just been plugging/unplugging (pretty annoying, but necessary).
