Looking to place an aftermarket stereo in an Infiniti J30 w/ Bose system. What sort of harness is necessary? The current headunit will power up, but no audio playback. All connections to the deck are ok, so it must be internally in the deck. What options are available for replacing this headunit? What aftermarket parts are necessary? Mounting kit, harness, sure. Is there a specific Bose adapter required? Thanks for the help.
