Radio Removal Keys

[eje]

to add some clarification - There isn't just no power at the USB. There isn't any power at the solder connection. (actually @.2v). But the stereo works in radio mode.
If the orange & brown wires are the main power source for the radio unit and I can't measure voltage there, why would it work at all?

I was able to get it powered up by plugging the Bluetooth module into a USB port in the cigarette lighter plug

I've found the orange wire (power from the ignition) has no power. The red/black wire (always hot) does have power, so the stereo always has power.
Don't think I want to connect it to the red/black-always on
