I want to invest in a Xiaomi Mi Box to cut the cord and am really attracted to its low price point. However, before buying does it support a receiver? If so does it come with a native guide application or is that on Android 7.0? If not is there an Android TV that runs 7.0, is stock, and is cheaper than say an Nvidia Shield?
What "receiver" are you talking about ?
Audio receiver = AVR ?
TV Tuner = USB TV tuner or HD Home Run Networked tuner ?
What Guide are you talking about as well ?
A Over the Air TV Electronic Program Guide ?
Girl Guide ?
You questions are not very clear.
