I sent my 07 RG stereo out to iron cross a few years back and had them install a headphone jack, the headphone jack is activated by the speaker switch on the dash . A couple of weeks back the headphone jack quite working, it's not the jack there is a headphone indicator on the stereo screen that is no longer showing. Has anyone had issues with their speaker switch, they are $85. so I don't want to trial and error the thing but not sure what else it could be, also not sure how to check and see if its bad. Any suggestions?
