What years were pre-wired for voice control? What does this mean? Is the wiring harness already in the car?

I had voice control pre-wire on my '04. Wiring harness is tucked into the LR corner of the trunk, adjacent to the electronics stack (if equipped--DVD for nav, CD changer, etc). In addition to the module, you'll also need a microphone (plugs into the overhead console, installs into the headliner; should still available new from Jag dealers.) and the appropriate fiber optic cable/extensions. While you're in there, and if it's not already equipped, it's a nice time to add the Bluetooth phone module (standard on '08-09 US market cars), and maybe even a CD changer (if it still works).

Once all in, and once trained to your voice, you can control infotainment and HVAC from the steering wheel button. I sourced the voice module off eBay, the BT module from a junkyard car, the correct fiber harness from Terry's Jags and the mic from Harper Jaguar. At that time (4-5 years ago now), I also installed a junkyard-sourced CD changer into mine; that changer died in the past year or so.

Ideally, you should add all the added modules into the car's ecus via SDD, but it's not critical to do so.
