Hey Sandman 1519,
Thank you for posting and welcome to the Bose Community. I would love to answer any questions you may have about your Wave system!
Yes the Wave Radio IV does feature a built-in AM/FM radio that you can access, if the signal is weak for the system you can also add an external antenna to the system via the 3.5mm input on the back of the system.
If you have any other questions please do let us know and we would love to assist!

I had a little trouble with my FM reception on my Wave Radio IV, so I purchased the FM antenna, as noted above. It has truly resolved my issue and I now have fantastic reception. I hang it behind my radio and it works great.
