I'm about to reinstall my riocar in my truck with a tuner module and wanted to check a few things first. 1) Does anyone know if the voltage in the line between the Sony wired remote and the tuner interface is 12 volts (I guess this would be the "ADC input"). 2) Is the 22K resistor actually in the tip of the Sony remote or built into the tuner interface (I can't tell from the Developer Information Page).
