Vehicle Sound System
This refers to what kind of sound system the vehicle has. Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

Why did you choose this?

Harness doesn't seem to match color specs of factory harness. Can you help?
Justin U on Sep 13, 2014
Best Answer: I don't recall an issue figuring this out. In my experience, depending on colors alone is going to cause you grief. I found the wiring harness guide for the Camry, then manually cross-matched based on function.
I've since removed the stereo from the Camry and reinstalled in another vehicle, so I've lost my original notes.

Bear in mind, this harness is for a Camy XLE with the JBL amplifier, to connect to a new radio that has pre-amp outputs. So a very specific use.

I'd recommend going to toyotanation .com and search the forums for "2005 XLE" and you'll find some good specific advice.
