Yes you can tell the difference. That's the only way I know to update your operating software on it. I ck every month or so to see if there are any new updates. Like I said it painless takes less than 5 minutes to do it. You download the update file on the sd card put in your unit and power it on and it reboots itself.
Just be sure to look what version your running, maybe yours was updated already mine wasn't and I bought it 4 months ago
