I didn't look at it real close because I am not interested in it, but I think there is something on this Richmond that has to be bought to make the whole cellphone communication/control thing work...back when I was reading reviews on this unit I remember people whining about having to buy an extra optional part that they felt they were mislead into believeing that it came with everything needed for the wifi to work...I dunno...having the touchscreen readout is good enough for me...
