Has anyone played around with the onboard gps to plan for a roundtrip or the maximum distance you can go before the battery dies out? I'm interested to know in order to plan for my next big road trip if the nexus 7 can perform what I want. I'm sure you are already aware that you have to set up your route before you jump out of the house. So far I figured out that if you use the automated GPS system, if you try and multitask you get kicked out automatically jump back to the standard navigation that google offers. If you suddenly change your direction, Google map will automatically correct your path, even though it might not be the best path since it does not have live access once you are in your car.
