OEM Navigation Connectors
I need some advice regarding the connectors for my OEM Navigation Head Unit (I have a 2003 Toyota 4Runner).
Here is a link to pictures & pin descriptions (basically what I know so far)
What I am looking for is a confirmation (or information) regarding the pin descriptions I listed. The names of each pin (e.g. ACC+B) are out of the schematics book, so I know they are correct. What I'm interested in is what each of these pins actually *does* (i.e. the pin description that I listed in parentheses).
I also am trying to find out where I can purchase these connectors. I am interesting in creating a pass-thru type of interface, but in order to do that, I need to purchase connectors! So, if any of you know who might manufacture them, please let me know. The head unit/navigation screen is made by Fujitsu Ten.
