Hello,

I am installing many handsfree kits in newer Chevy and GMC trucks. I have noticed that the radio stays on until the door is opened. I was wondering if anyone knew which fuse (if any) controls this function so I could tap into it for the ignition lead on the handsfree kits. I looked at a wiring list for a 2005 Chevy truck on this site and it says the ignition connection on the radio is Class 2 Serial. What does that mean?

Also, does anyone know about a mute lead on the radio?

Thanks,

MasterMarine

the radio is controlled by a databus wire, there is no power wire that will remain on until a door is opened. The only way to acheive this on the newer GM products is with a databus interface, or you can build a RAP relay setup like the ones in the relays section on this page.

Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.
