References to a "small one" suggest to me that you have voluntarily agreed to convert your existing V6 into a 360-master, and also been given a multiroom 360-mini.
You will be sent the new voice-activated remotes for your new 360, and a day or so afterwards, the "upgrade to 360 now" app should appear on your V6. When you are ready to convert, make sure you have made a note of any series-links you have, and watched any recordings you want to - the conversion process is a complete reformat with the new 360 software. Once you are on TV360 your boxes are no longer TiVo/V6.
