So I have a new 2007 package #4 prius, and I'm wondering if it is possible to upgrade to the factory navigation system. I already have the steering wheel controls and the map button on the dash. Could the factory navigation system be added easily? Thanks for any help.

For a few hunderd dollars you can get a good aftermarket portable GPS unit that is better than Toyota's. Garmin & amazon.com have good prices.

You can sometimes get the parts cheaper, used, but good luck with that. I would recommend an aftermarket add-on.
