Other then the intercom or cameras being viewed on touch screens which we don't have integrated, are their any other limits? We currently use two tablets for touch interface. They get used about 15% of the time. We mostly use remotes in the rooms unless we are listening to music. Our dealer told us they would be limited but we have not had any issues since we switched to them from our original mini screens two or three years ago. Thought it would be an interesting attempt at a bigger touch screen spending $700 less then a new touch screen. Thanks for the input!!
