So I thought it might be neat to get a Scangauge to watch my mpg since I don't have that readout in my plain jane 2006 Elantra. I go to the website, it says virtually all cars since 1996, I get excited, read about the unit some more, get ready to order, and a birdie comes and sits on my shoulder and tells me to just check the incompatibility chart to make sure it fits the OBDII connector. Never assume though. But no big deal. A short list of incompatible diesels, the Lotus Elite, and......one car won't fit the connector. -One- stinking car, out of, I guess, every car made in the world since 1996. The 2006 Elantra. It's quite hard to fathom. I'm still dazed. Hyundaitech, why on earth do you think Hyundai did this? Does this mean I'm at the mercy of only the dealer for diagnostics? Or, (looks heavenward), is there an adapter that everyone else uses to run diagnostics on this rare bird? (and might be used to run the Scangauge?) Will await answer with just a bare bit of hope. Thanks!
