Hi all, I just got a Prado and figured that I'd like to do more with the SatNav. This is what I've discovered thus far: The Sat Nav is made by Denso. It outputs bog standard VGA using RGB (just like your computer) the Touch screen sends button and touch scrren signals to it via the AVC-LAN (no details yet). There is no way to get the raw GPS data from the unit (without cracking it open). The display unit is made by Fujitsu Ten (owned by Toyota, DENSO et al). It accepts the VGA signals, supports a bogg standard Toyota audio system connector and is able to take NTSC coposite vidio in. It appears to us the Reverse sensor (probably not fitted) to turn the camera on and change the screen to display it - regardless of what's going on with the NAV. The map data on the DVD is in a format called KIWI, although fully specified very little else on the Net about it (http://kiwi-w.mapmaster.co.jp/index_eng.html). So it looks like it should be easy enough to put a reversing camera in or set the system up for an alternate video input. Getting access to any GPS data will be a different story. Putting a different MAP DVD in is going to be a real challenge too - however, I'm going to see if I can understand the spec enough to read the DVD I've got and then try and make a custom map.
