Yea I'm already a step ahead of you there. I have installed aux and bluetooth myself! I have aux soldered directly onto the board. I even have modern bluetooth with a2dp set up as well! All feeding through the stock radio to maintain that stock interior look, all while keeping a pure signal for my audio. I just need the tape button to access that audio though =/.

With regards to the detail, yes I figure it can't be coincidence that the tape button suddenly stopped working after they had it. I was just hoping I could find someone here who has experienced a similar issue and may have found a solution.
