I decided to upgrade my 1.5's single-din radio. I picked up the JVC single-din nav unit that was optional when the car was produced and installed it yesterday. It would have been really easy (other than running the different ipod line) because every wire, including the extra GPS antenna, was already installed in the car. Except one. Apparently the Sirius option requires an extra power and ground lead. The original wiring harness's wires don't match the colors in the JVC documentation, so I wasn't sure which I should splice for power. Right now, I have all the extra devices behind the VDS, but I need to find a power lead. Any suggestions or recommentations on where I should pull the extra power from?
