I've tried searching on the internet and can't find a wiring diagram. I have a constant but no other power Ie: ignition Its an 8 pin connector, 4 x 2 top 4 are Pink (speed) blue w/yellow stripe (unknown) yellow (unknown) black (ground) bottom 4 are purple (reverse input) blue w/red stripe (monitor control out) red (unknown) orange (constant) any ideas?

Bought a JDM Pajero and has this navigation installed. Anyone have G-90? Anyone got one working in North America and is there a compatible NA map disc out there? If not I will try to install CNDV-80MT and post the results.
