Toyota Estima 2013 Head Unit Schematic.

[MAYUB]

Can someone kindly point me to the Toyota Estima 2013 head unit loom schematic to figure out and complete functionality of new aftermarket Chines head unit. I posted pictures of OEM Panasonic Head Unit with  and without loom connectors plugged in. 

I have connected new unit, CD play work fine and produce good sound in all Speakers. It means power to unit and Speakers wired correctly to the new unit however it did not pick any radio channel of AM as FM.  I suspect that might it need amplifier voltage. Antenna plug was inserted formally into the socket. same issue with SW switches setting and wires need to route into correct points etc, Your help will be appreciated.

Update, SW switches are fully functional now, new unit need teaching by push and hold through the system firmware. Only radio functionality is the remaining issue to find and tune radio channels.
