Summary: Best radio I have ever owned. I have used alpine, sony, and JVC. I find the pioneers are just the ones I like the most. Very easy for me to use. Built in crossover helps for components. Use it in all my vehicles.
Summary: PROS - Playing music through an iPod is a breeze. - Plays AAC filetypes (songs purchased on iTunes). - Plays CDs. - Illuminates in red or green. CONS - Using the main control knob to navigate through option menus takes time to get used to (and is still awkward after that). - Automatically starts playing a song once an iPod is connected using the iPod USB cable. The reasons I purchased the 3200UB are that it connects to iPod via USB and plays CDs.
Summary: Great head unit for the price. Sound quality is good(clean, undistorted). USB input is a great feature that is a great plus. CD's are practically unneeded if you use a 32GB USB drive with all the music you can possibly want to hear.
