I have white noise even when the car is off. It does not get louder with the engine rpms.

Connected just as Pac instructions say:

Crimped 8 speaker connections from radio to Pac harness
Connected yellow, red, black from radio to Pac harness
Connected blue/white wire from radio to blue/white on Pac harness
connected light green from park sensor on radio to black ground on the radio

Any ideas why I would have white noise coming from speakers? It is not very loud, but it is there.

I'm sure Mark will chime in to help you. Might need ground loop isolators??

Not sure where I would hook them up as I used the speaker wires to hook it up, not rca's.

My 08 did the same thing. After weeks of troubleshooting it ended up be a bad wiring adapter. That blue box was the issue. Double D Mods sent me a replacement and that fixed it.

Wow, that was the problem. The Pac module was no good. Put a new one and and all is good.
