What's the 2006 Chevy Colorado aux input location?

If You're talking about the AUxButton, that just exists for an optional CD changer, and likely isn't what You're looking for. Sadly, other than that port for the CD changer on the back of the head unit, there isn't an AUX input on the 2006 Chevrolet Colorado. Don't despair, though. There's a reasonably priced input You can check out: The iSimple Gateway ISGM575, which is available from Sonic Electronics for only $115; it even has free shipping. This kit lets You have an auxiliary Audio port for Your iPod/Android device, charges Your iPod, has Satellite Radio and bluetooth modules, and delivers digital quality Audio. Check it out if You really need an AUX input on this vehicle.
