I have 2007 ES350 without the Navigation unit but I purchased the Lexus Navigation unit which I want to install. When I popped my CD/Radio unit I could not find the harness to install the navigation. Can someone help me how to install this factory Navigation unit? (Where is the harness? if does not exist where can I get it? How to install it? etc...)

Thanks in advance.

 

I am in the same situation. Did you get the harness you needed ? If yes, please let me know where you got it .

Thanks
