I recently purchased a Bel RX65 and a hardwire smartcord and am very happy with my decision. I figured I would go ahead and try to do something a little different with the install. I ordered a custom Z mount from Country Joy and the quality on that piece is top notch. I would post a pic of that, but mostly everybody has seen a mirror mount before. So here is a before and after pic of the smart cord mute/volume module.

Nice,
I was thinking about doing something similar with my Solo 2

 

Thanks. Let me know if you have any questions. The mute button is very handy located there even though this thing hardly ever falses.
