Summary: I chose this unit since most of my music is in digital formats and I was tired of burning cd's I have music loaded on a 32gb flashdrive since I am not an "i" person and it handles my mp3's very well. The most important thing is to make sure your music is of good quality. My only gripe is that you need to use the remote to control most of the settings which means you can only tune your sound while parked.
Summary: $110 is short money by anybodies standard. I bought it because of the Sony name. I've owned lots of Sony products over 40 years and have never been disappointed, I figured this would be no exception. Man, am I impressed. The unit comes with everything you need: line-out RCA's for all four channels, a dedicated subwoofer out, and line-in. An iPod to USB adapter is included, an iPod Classic fits with room to spare.
Summary: I really like the idea of this product, and in general this is a great unit. Using the remote control makes it all worthwhile, but the central knob on the radio is hard to use while driving. After using this for a year, it still works, but the internal connection no longer reads the iPod, so a major function is gone, it just does not recognize the device. Now I just use the external USB port and control the iPod manually.
Summary: Received this head unit very quickly. Unit was installed, and the FM Tuner works fine, but when you plug in a USB Memory Stick, the display shows the Artist, Song Title, and counter.. but no sound. Same with the iPod and iPhone. It LOOKS like its working, but no sound at all. Change to the FM Tuner, and there is sound. Spent 2 hours online with Sony Support, to no avail. It turns out that the Blue Wire is NOT for the AMP. It is the Blue/White Stripe.
