Summary: device seems incapable of loading more than about a gigabyte of music without freezing on startup. controls slow if you get it to turn all the way on. Updated the firmware and it still freezes on startup. Who would release something so terrible?
Summary: I bought one of these RCA M4308 and I had nothing but trouble with it. After loading my tunes on it it took forever to "build the database". It often froze up on me requiring another long startup process. Quite annoying if you're just about to start an exercise routine and it tells you it'll be a few minutes before you can get any music out of the darn thing. When it was working properly the controls and functions weren't very user friendly.
Summary: I was really dissappointed in this little player. It was nice and light, great for running, controls looked simple... but trying to put music on it is rediculous. It is terrible... the system does not allow you to create playlists on your computer to then put them on the device. The device makes you copy music from your files onto a media player then you can put them onto your RCA computer library and then you can put them on the device. WHEW!
Summary: Everything on the unit works just fine and is fairly easy to use. The only problem with the device is that it has a time stamp for files of 1980 with no function for changing it. The company told me to update the firmware but problem still exists. All of the Opal models have this problem.
Summary: Pros: Wal*Mart didn't hassle me about bringing it back. Cons: This piece of doo-doo locked up and failed to boot three times in 48 hours. Also, I can't say anything BAD enough about Audiovox's "Customer Service." Summary: Don't waste you time, money and good nature. A year or so ago I bought a new car with a nice factory stereo, which in addition to playing MP3 and WMA formatted CDs, had an 'AUX' input for portable stereo devices.
