Thank you for the replies. I've been doing some research as well and have come to the same conclusion. I am greatly disappointed though, not because people don't currently make them, but because people don't share their builds enough for others to make their own... I have spent about 3 hours looking for a build write up, with no success. Perhaps I'm just looking in all the wrong places? *sigh* I can watch my mileage the old fashioned way, it's just more exciting to try and beat your trip mileage, or your spouses mileage.
I've been without a mileage gauge of any kind for about 3.5 years now. I miss it...
