Hi Guys,
I bit the bullet and bought an SPH-DA120 radio for my Audi A4 B7, bought all the relevant wiring harnesses and radio adapters but having no joy getting power to the HU.
Couple of questions please if anyone can help.
1. does the parking brake cable need to be connected for the unit to operate ?
2. There are 5 wires from the pioneer loom that plugs into the bottom part of my ISO adapter, this part of my iso adapter has no connection for the Dash Illumination or the 12v ignition switch, there is also no wire that connects into the system control connection part of the loom
