actually i dont think they should make a screen... it would just increase the price of the unit and it would make it harder to install (need to be in a place where it could be acessed easily) where as the bluetooth offers you the ablity to control it within range by a palm, certain cell phones, and as of 07 ces laptops (pc's in general but u may have range issues) with a bluetooth adapter (herd its great to by a bluetooth mouse and use both)
