Cheap Navigation
 

If you have a PSP with FW 1.50, you can now run a navigation program. The link and video of it working can be found HERE. The GPS antenna is about $80 on ebay, if you already have a PSP thats mighty cheap for navigation. I used to have a modded xbox in my car running XBMC for all my media needs. What I think I am going to do this time is, install a dock to hold the PSP on top of the dash. Get some kind of wireless audio either bluetooth or RF. Get the HDD for the PSP and put all my songs on there. If it works I'd like to get wireless USB going on the GPS. If I can get everything wireless I can pass the PSP around the car for who ever wants to control the music, and install the remote somewhere on the steering wheel so I can control it while it is docked. I am going to have to see how well I can see the PSP on my dash tomorrow to see if its worth it or not.
