Tom , i have not removed my head unit yet but as a question if in case this X3 does have DSP by locating the #2 12 pin adapter can i just keep that second 12 pin connector connected to the head unit if that solves the no audio issue? or is it a must to purchase the DSP unit for the icelink ?
I just dont think i really have DSP on this b/c there is not DSP button on the radio like the picture below or does the button not necessarily mean i have it or not ?

Thanks
