I've been thinking about fitting one of these since Macon last year and thought it might liven things up for my passanger....Basically i am considering two options.
1. Buy a proper tripmeter, now they seem to have 3 type of sensor, Speedo, Gearbox, Wheel. As i own a GTA i guess i got to fix the latter as the Gearbox sensors seem Subaru/Lancer orientated. Anyone ever had a go at fitting this kind of device?
2. Download some free software for my TomTom such as Tripmaster http://www.webazar.org/tomtom/tripmaster.php?lang=uk Anyone every used this?
