Please help me. I've got a 2000 jetta. Trying to replace 2nd aftermarket stereo. Originally I had a jensen head unit and I took it out to put in a JVC unit. I connected the wires from the jvc with the same color wires that went into the jensen. I think they are all correct. While doing so, the red (ignition?) wire touched the yellow (battery?) wire and I blew the fuse. I changed the fuse and now all that happens is I can eject a cd or load a cd into the head unit but it soon shuts off. It will display the clock but that also soon goes away, even without the key in it. I am pretty sure the radio works fine becuase when I touch the red wire from the head unit to the yellow battery wire it powers up fine with no key even in the ignition. Did I blow something out? Please help me I really dont know what to do from here.
