What should I look for in a Dock & Play radio?

Display size
Not surprisingly, the bigger a Dock & Play radio's display is, the easier it is to see. Also, the number of lines in a display determine the amount of information it can show you.

The bigger the screen, the easier it is to read song and channel info.

Size and design
The amount of dash or console space you have available might help determine the size of the satellite radio you get. Some are designed to use as little space as possible, giving you more installation options. Aesthetics certainly play a role, too — you'll probably want your radio to look good in your car, and to blend well with your home stereo components.

Wireless FM transmitter
As mentioned above, a wireless FM transmitter helps you use a Dock & Play radio with any in-dash stereo. The more frequencies on which an FM transmitter can broadcast, the better. More choices mean you're more likely to find an unused FM frequency. This is especially helpful in large cities with high FM station density.

Channel presets
The more channels you can save as presets, the easier surfing and finding your favorites will be, especially in the car.

Internal memory
Some Dock & Play radios will automatically and continually store whatever you're listening to, which can be quite handy. This means you can pause live broadcasts, rewind, and fast forward. The memory buffer replaces the oldest content as it gets filled up. Usually, this memory is erased whenever you turn the power off.

Song memory
Many Dock & Play radios let you save the names of either song titles or artists , then will alert you whenever they're playing, no matter what channel you're currently listening to. You'll have the option to switch over to it from your current channel by pressing a single button.

Info extras
Some Dock & Play radios are able to show scrolling, customizable information on their displays. Usually, these are either sports scores or a stock ticker. In most cases, you can select the teams you'd like to see updated, and the stock symbols you'd like to follow.

A wireless remote gives you handy system control in the car and at home.

Wireless remote
Most Dock & Play radios come with wireless remotes. They make controlling the radio in the house (or from the backseat of a car) much easier.
