Crescent Control on a 2006 Country Coach Prevost

hi considering updateing my creston system any sugestion

Di you do the upgrade and if so how difficult was it?

What are you considering updating the Crestron system to? In the L-series Countries and Legendary's, Crestron components are used for lighting, shade, climate control, as well as audio and video system control. Even the stereo amplifiers are Crestron brand if I am not mistaken. I am not discouraging you from doing so, but be aware that replacing all of that equipment and doing what is necessary to have those functions back is going to be a very comprehensive deal. If you simply intend to have the software or touchpanel interface updated to include a/v components you have had to change over the years, that is a different story. Providing that a programmer can get ahold of the original source code file for your bus, (may be able to through Miles Circo), than you are probably looking at $2-5K depending on how much time is involved for the number of components that have been changed and need reloaded.
