I also spoke with Charles at Rostra. His number is 800-782-3379. He matched the color and then refered me to there East Coast Rep. Eddie at 203-915-0049. He then set up with an local install shop. They do not sell direct. I called my local Toyota Dealer they did not want to be bothered. The install (One Stop Car Audio, Northfield NJ) cost me abot 150.00, about 200 for the parts, the speaker / on / off / low / high swithch is installed on the kick panel. It is definately more prone to false alarms then my Sienna with a factory unit, I do not know if it has anything to do with not being the exact factory unit / or something not done correctly on the install. I called Rostra said if the bore holes are not clean, or the wiring is is not perfect, it can cause this, along with weather conditions. But well worth it.
