There's a product on the shelves called "silicone repair tape." It sticks to itself, and provides a bomber moisture seal. If you are going to plug the car charger into a standard cigarette-style outlet, a few inches of this stuff will insure a good connection.
I've recently found a waterproof case for my 7" tablet. It's not without issues, but I think I can make it work. While designed for the Samsung Galaxy, it fits my Lenovo tab nicely. It's an Aryca case, which appear to be just coming onto the market. I have one in hand, but sourcing is sketchy. I'll be field-testing soon.
I've been fiddling with the Dualsportmaps app, and think it will be very useful. I see that's what you're navigating with. I'm not yet ready to give up my dedicated GPS, but I'm going to give Craftycoder's product the college try. While I'm doing that, I'll have my primary GPS, the tablet, and likely a spare. I hate being in the boonies without reliable navigational information.
