On February 24th, G1 owners can have full color, 3D, turn-by-turn TeleNav navigation in their hands. The software features voice recognition, traffic alerts, and one-touch re-routing. The first 30 days are free, but after that you've got to cough up $9.99 per month. Considering the massive database of maps and points of interest at your fingertips, that might be a pretty good deal. Sounds like a good way to drain your battery, though.
We'll have a video review as soon as possible, and I have a feeling I'll be using my windshield-mountable charging cradle from WirelessGround. There's a video review coming soon for that as well.
