Check for compatibility. The docks in some table radios won't accept every iPod model. The latest Apple products are a particular worry as the company has significantly changed its docking port, meaning that an adapter that might or might not fit the radio could be required. Some table radios are shielded to allow docking of an iPhone without getting interference from the phone signal. Reviewers say that some models without shielding can still be used with the iPhone as long as the phone is set to airplane mode.
Digital or analog? Digital tuners let you scroll through stations with the click of a button, rather than having to precisely turn a knob until you pinpoint a specific frequency. You can also store favorite channels in presets that can be instantly recalled, but make sure your radio has enough presets to hold all your AM and FM favorites. Analog tuners do have some advantages, however. One is that tuning is more flexible, allowing you to dial in a hard-to-capture station that might elude a digital tuner.
Check the warranty policy before buying from an unauthorized dealer. Some table radio makers have restrictive policies regarding who can or can't sell their products. For example, if you purchase a Bose radio from an unauthorized dealer either online or in a store, the company says you won't be covered by the manufacturer's warranty.
