I'm trying to figure out how to add a Bluetooth module to a 2006 GS430 and found that the GS300/GS430 2006 at least has a "Optional Connector (Audio System)" to the head unit located in the trunk. Has anyone tried to add an audio signal to this or know anything about it? I believe it might be an CD Charger input as it is labeled "CDL+".

You going to have a winner on your hands if you figure it out. Would love an aux input option on the 06 gs430 as well.

a few months ago when I was looking into it I found this. I think it’s for adding a backup camera but I’m not sure.

hope this helps.

 

Maybe this?
