Really interesting idea. What program are you using, the one that is visible on the unit in the tank bag?
Is tracking based off of cell phone signal, or GPS? If I wanted to use google earth with it, couldn't I just plan out a route, on my mac or pc, email it to myself, then open it up in google earth on the tablet and be off and running? Seems way easier to me than basecamp, 20 track limits, etc. etc. that I had with my 60csx that I broke in half last weekend.
