I have set up all the IP commands for my Dune HD Smart D1, and all work as expected. I want the navigation commands to repeat when holding down the button. I turned on the Repeat while held in each command. I have tried a number of different values for the Ramp settings, all with no success. They work for single press only. I have successfully set up repeating IP on my Roku, so I thought I was on the right track. Anyone else have this experience, maybe a solution? I forgot to mention, I am using a URC MX-5000.
