Im not even sure im gonna get a navi......but if I get a pocket pc, i will always be able to get it if I wanted to. As far as the program goes, like I said, I installed it in my friends RSX and it works great. Tells you everything, dyno is 90% accurate, can reset CEL's, and tell you why its on, real time graphs, fuel, etc.....a great thing for under 250 bucks.
