I am bench wiring the T)1, RR & AVIC-W8400NEX. The RR instructions are ambigiuous and there are no instructions with TO1. I have connected the wires but am not sure about this component of TO1.
Does this need to be connected for the AVIC-W8400NEX or is this redundant
Regarding the four wires for the OEM camera connections.... Do I need to connect them to the vehicle or does the TO1 harness address that integration. If not, where do I find the 20Pin connector as listed in the RR instructions (2011-14 NON-JBL Sienna). The only 20Pin connection behind the radio is the main power one
Last of all, I am also adding a SXV300 Sat tuner. For Navigation and Satmusic, Do I need to add the GPS connection to both the HU and the SXV300 or can I just add it to only one, Tuner or HU and the Sat/HU interface will allow both (Navigation and Sat music)
