70runner Posted August 13, 2009 Report Share Posted August 13, 2009 I realize use of the mute wire for grounding pin2/slot 4 of the harness is simply a convenience - proper connector. A question I've seen asked, but not answered - will relocation of the mute wire effect use of onstar muting via the GMOS-LAN-01 adapter? Quote Link to post Share on other sites
tracknine Posted August 15, 2009 Report Share Posted August 15, 2009 no, the module takes car of muting the radio itself. the mute wire is really only needed with 3rd party bluetooth adapters, ie parrot Quote Link to post Share on other sites
