2013 JBL stereo install with Nav

Hello, I'm trying to figure out how I can get the following harness for a 2013 JBL stereo with Nav the one that is in the picture. My assumption is this is what connects the navigation to the HU? Please correct me if I'm wrong. I asked the parts department at Toyota about this and showed them the pic and they couldn't find anything for me. Any help would be greatly appreciated.

 

Doubt its available to purchase on its own. My guess is, its only comes with the radio its intended for(not available as an individual part).

What are you trying to do?

 

Put a 2013 jbl touchscreen with nav in my 09.
