I just bought my friends 2007 Camry SE from her. It has the factory Nav that has never been updated. I want to do two things:

1. Update to the latest software (v9.1 I'm guessing based on ebay). Where's the best/cheapest place to buy the disc?

2. Make it so you can use the Nav while driving. I found some very old threads on some fixes but they don't appear to be a complete fix. With our VW we simply downloaded a program, put it in the Nav, and it allowed use while driving.

Thanks for any help. I'm a noob to this car/Nav!
