iPod nano comes in 5 stunning colors and is designed to provide hours of entertainment with maximum portability. Its 2.5-inch Multi-Touch display lets you see more of the music, photos, and videos you love.¹ And it has built-in FM radio as well as support for Fitness Walk + Run and Nike+.
This may be a good product for simply listening with headphones, but totally useless if you plan on using it with your car audio system. Bluetooth pairs, but will not play correctly. Plug via USB and system will not read nano. After reading through forums I discovered that apparently apple doesn't want their products to work with car audio systems and who knows what else. So, if you want a player to work with your car audio system, do not buy anything made by apple. Sad because older ipods work no problem.
