Q: What is the difference between the CM5905 and CM5907?
The CM5905 and CM5907 are nearly identical in appearance in functionality. Both radios feature an AM/FM tuner, but the CM5907 also adds a weather band tuner. Thus, the top right button on the faceplate of a CM5905 radio is labeled "AM/FM", whereas it is labeled just "BAND" on a CM5907. For the purposes of our products though, the radios are the same.
