I'm going to step out of the thread after this because it's turning into more of an argument, which was never the intent, and this forum is better than that. However, you keep bringing up cost, and I don't think that is an issue for anyone looking at this functionality. It is custom niche hardware developed for a specific vehicle and I don't expect it to be cheap. I do expect it to work well, though, and that has been the recurring unanswered question of the thread. It is surprising to see such a poor warranty policy from the company and a complete lack of real user data out there. That's the only point being made. Glad to hear you are happy with the nav functionality.
