Good unit, but OS is outdated and screen is TOO small.

Summary: I bought this replace another similar unit from Pioneer. The OS is identical to the one from several years ago. NO IMPROVEMENTS. And the screen is about 1/3 to 1/2 the size of that unit, which it makes it a lot harder to read. Don't get me wrong, this unit is good. Pioneer is the only thing I buy anymore because of the reliability, and I personally like the sound characteristics of their head units.
Summary: The sound quality is good, especially for the price, and that is why this radio gets 3 stars. I mated this to the Sirius Satellite receiver, and the sound is good, but there is no provision for directly typing in the channel you want, so you will find yourself scrolling through channels or presets while you are trying to drive. The remote is also just a channel up/down button, but no keys. The USB drive plays songs in alphabetical order.
