Morning Al,
To answer your question, your Crestron system will need to have a revision in it's programming to accommodate a different brand of TV. I have a whole new program that runs much more streamlined than the original program. I know that your manufacturer does not give out their original source program, even tho you have spent a fortune on your coach, they hold on to the program as intellectual property. No worries, as I have created a brand new program that I offer to my customers. I do not hold the program "hostage" as some manufacturers do. (such as what Mr. Browder mentions below).
No doubt, you have a quality, reliable Crestron system. Inevitably, things need updated or changed. TV's wear out or break and need replacing. Satellite systems need updating, or DVD players changed out for BluRay's. What I have developed is a system of allowing you to have these changes made, without having to go into a service location.
What I would like all POG members to be aware of, is the fact that they do have options. Without question, there are great systems and manufacturers out there, however most of these manufacturers want you to come to them for work or updates. This thread was created simply to inform POG members that they do have options. Not all manufacturers offer the full capabilities or features that Crestron offers. Uii-Gui has expertise in the luxury transportation industry, so we "talk your language" and fully understand what you need.
