Does anyone know if there is a stereo wiring harness kit available for an 06 hummer h3? Wanting to install an aftermarket stereo/nav system, without cutting factory wires.

I haven't done one of these yet, but I did notice a tech note in the PAC OS2-BOSE about connecting extra databus wires behind the radio to get all the functions to work, I would check with them. www.pac-audio.com

I've done a lot of the H3's,,,doibuy is right, use the OS-2Bose and connect the 3 purple wires from the two factory connectors. There will be 2 in the large connector and one in the smaller connector,,,the bulletin is listed on their website.
