Ok so here's the deal. I have 2 4runners, a 06 v8 w/o nav and a 08 v6 with nav. I have a complete nav system from a 07 ( radio, Mic, Bluetooth buttons, camera, camera wiring for the gate, misc radio plugs off the back of the nav radio etc) that i never installed in the 06. The wife loves the 06 but wants the nav system in the 08 so now HAPPY WIFE HAPPY LIFE is in play.

I did find different posts to make this work but they are all over the place

Here are the questions:

1 - The gate camera harness that plugs in somewhere in the quarter panel. With tghat harness installed will that allow the camera to work without splicing into the harness.

2- where on the radio plug to the amp do i need to go to make the voice work.

3- if i got the rest of the OEM harnesses for the voice and camera would that eliminate all the splicing?

4- where do i splice the vss off the oem non nav harness into the vehicle.

5- is there really a big radio plug for the nav behind the cluster as i have read or is that b.s.

BTW a new non oem radio is out of the question. I blew my budget for the next few months on new wheels and tires for the '08 besides i already already had this setup.

I could be mistaken but I think there's a missing item or 2 on your list for the NAV system, I'm sure I have read that's there's a NAV computer or ECM, a antenna and or something similar that you will need as well, other than that I can't help.

I found the antenna it is number 2 in this diagram, but I couldn't any other part that I think you maybe missing.
