There is a small red L.E.D. just to the right of the Tune/Display knob. It seems to come on periodically maybe even blinks once and then it is not emitting. What is the function of this light and what does it indicate? I am a bit befuddled as there is no recurring theme to it at this time.:confused:

Thanks guys! I didn't even know it:thumbsup: had that feature. I bet there is more on board this vehicle I am not aware of.

watch out for the mysterious red wire in the engine bay next to the battery

My Envoy has the same red LED, but it's not for the factory alarm. I know because I don't have the factory alarm.
IIRC, it only blinks when the key is in the OFF position.
Maybe something to do with an anti-theft for the radio?

yeah more precisely it is the anti-theft system of the Radio, not the cars alarm
