I updated mine and it never worked again. I took it back for another which I have not updated. My system version is v2.0.1 and I was using a windows ME PC. After the update the only change I saw was the App which went from 1.1.4.02 to 1.1.4. a downdate !! I am also new to this so please excuse me if it looks like I'm talking rubbish. Maybe someone knows if there is any info on what changes you can expect from the updates so you could decide if it's worth the risk/hassle. The Marantz site is very lacking in this respect. Philips is better.
