I thought this might be an aftermarket installation problem.
My guess is that your short is somewhere between the connector and however the connector wiring was spliced into the factory wiring.
Take out the head unit, disconnect the connector, and look at how each wire is connected to that connector. I'm sure you'll find the problem.
