Also included with this system is an FM radio, but unfortunately you have to source out your antenna. Why it is not built in is a mystery and further adds to my theories of how much of a low end device this is.
So, if you can be bothered, you have a radio as well as support for your ipod. The unit does feature a small remote control which is very light and does seem to be a bit of an afterthought, although it served its function for me.
So to recap, there is an aux port at the rear for connecting a music device that is not one of Apple's (i.e. ipod, iphone, etc.). For Apple devices there is of course the port at the top. And as a secondary option there is the FM radio.
Don't forget, though; it's also an alarm clock with a decent sized LCD on the front and it is blue rather than red which most bedside alarms seem to be.
