I think, the only diference between de Non Navi system and the navi system is the the Pin that control de output to the speaker. The Navi system is not Auto-Amplifier.
I need some help. I have a 4runner 2011 with Non JBL stereo system. I bought the OEM Navigation radio and the OEM amplifier. But i dont have either wiring to install the system. How i install the OEM navi system and the Oem amplifier? Where i can find the wiring (cables) between the Radio Unit...
