I'm using the Navman 3100. Like others the sender went bad after 11 months. The factory replaced it under warranty. Since then no problems. I find it very handy backup to the fuel tank gage which like all fuel tank gages I've seen, are subject to poor accuracy. It also gives proof positive about mpg dropoff above 4000 rpm. It was real easy to tie into the GPS for mpg display.
