I just did it on mine...worked like a charm. You have to have the odo button pressed in before turning the key any. Once you're in it, you can start the car up and keep going through menus and change stuff. It gives a real time read out too..not delayed. I'm gonna use it on trips from now on lol.
you're supposed to read the article to know what that means ... that's ok... when the car is off it reads something high I believe.... it's like a reverse thing that tells the gauge where to go... so 000.0 is normal
yeah, I happen to think that's pretty cool myself... but I'm weird. I like the fuel one too... much more accurate, 0-18 is the LOW haha, I'll be hittin' that a couple times. That Low Fuel light will pop on, I'll shut my car off, and turn on this digital thing and tell my car it's LYING TO ME. lol. but yeah, it's good for fun and such
