Looking for a Jeff Herke arm cuff (with stand) for the Xterra.-----Also looking for a headphone adapter (cord with connectors) that I can plug into the control box on my Xterra 705 and run it back to secure it to the arm cuff stand (so the headphones can be plugged in at the back by the arm cuff).------Let me know if you have either one of these items & the price (shipped).--------Thanks, Del
