How do I use this head unit for off line GPS nav? Is there a program already installed on it, or do I need to purchase and install one? If I need to purchase and install, what program works best? It's in my RV, so if there is a program I can install that is stand alone that I can enter my RV length, height and weight so routes are developed with the dimensions in mind, that would be great. Thanks!
