I am doing a retrofit of a nav into a non nav 2007 es350, I got pretty much everything nav unit complete with DVD player and gps antenna that i got from a salvaged 2008 es350. The only thing I need is the play&play harness to complete the retrofit. Does anyone know how to get one ?

Here are the parts that i have for the retrofit, only need to make the custom nav harness, if anyone knows where....

I can tell you that you don't need the speakers and amp as they are in your car already. The head unit on the GPS is independent of the amp and speakers. Your concern is only getting your existing wires and the new unit plugs identified. Having done some work i found out that you may want to go back to the junk yard and cut off as much of the harness as he will allow and get those connectors for the new unit.

There is a service manual pdf for the es350 floating around the net that has the wiring diagrams in it or you can go to the Toyota site for $10/day and grab all the wiring diagrams for nav and non-nav cars.

I'll be watching your progress on this project.

Good luck.
