Sarcasm. Guess the tone doesn't translate over the interweb.
I hadn't had coffee so I was also grumpy.
I got a great education in GPS 101 here (now desiring Montana) and then learned of some cool apps and capabilities of my phone (motionX budget).

As a contribution I'd encourage those looking here for information to find the experts and read their posts. There's some great threads in this forum. BTW sorry for thread jacking the navigon thread, I know nothing about it.
