    Have you checked behind the port to make sure it's all still connected alright?

    I can't remember off hand but it might be #10, something along the lines of engine management.
    Can you start the car?

    As said fuse is the first place to check. Do you have an aftermarket radio fitted?

    I'm on my phone so don't have access to fuse diagram but there definitely is one.

    I think your cheepo cable has failed on you try another cable or take it into a computer repair shop and see if they can check it out.
