I havent come across a waterproof camera with a large enough lens to do well in low light. I have 2 models for you to consider though,
1. Panasonic DMC-TS1 - waterproof/shockproof 12MP and DOES 720p HD video.

2.Olympus - Stylus Tough 8000 12MP camera.

The panasonic will blow away the olympus in video quality and it also has a larger pens to collect more light. The panasonic also has 4.6x Optical zoom vs. 3.6, so long distance shots will be clearer.

I would say both are poor choices for low light, your best option is a D-SLR camera, they are sensitive to low light and can zoom much farther with telephoto lenses, however they are expensive and are not waterproof.

Sony has always put great lenses in their cameras. I like kodak also though. No brand is the best though, all the companies make a low end camera and a nice camera. Google your favorites and check out others reviews (youtube the model too for video reviews) and narrow it down!

you need a high speed internet connection first.

If you are the only one who needs internet access, plug the xbox directly in with the provided cable. If you want to share access with another computer you need a router.

If you want to be wireless, you need a wireless router AND a wireless access point for the xbox.

You should re-ask this question and specify if this is a tom tom or garmin or something else becasue it is different.

As far as my understanding goes, Tom Toms you can plug in and run an updater from the computer. (the updater us normally found on the tom tom accessed through the PC in "My Computer" )

Garmin, you will need to buy Streets 2009 for upgrading the maps. Its a bit more complicated, but if you get lost Geek Squad can do it for you. For some people $30 or so is worth the trouble saved. But it might go smooth for you. It took me a few tries to figure it all out.

Good luck! Happy Driving!
