V6 already explained above, but apps on VM's TV boxes aren't like phones & tablets where you download the ones you want - they're preinstalled by VM.
So you need to choose one of the more recent TV boxes that has Prime - V6 runs the same TiVo software as you're used to, TV360 currently being pushed by VM is fundamentally different.
Both need VM home broadband for an internet connection, different to your TiVo's which is inbuilt.
