Motorola's latest portable handsfree speakerphone offers a couple of enticing features. In addition to regular handsfree calling, the MOTOROKR T505 can stream music and calls to a car stereo via a built-in FM transmitter and also announces caller ID information for incoming calls.

Aesthetically, the T505 is chunky but quite stylish. A plain grey plastic finish means it will blend nicely into most modern cars. A large, removable clip easily attaches to the sun visor in your car. Like most of these units, it can be just as easily used outside the car – the clip sits neatly on a desk or table for home or office use.

Pairing the T505 to your Bluetooth compatible phone is as easy as switching the unit on and searching for nearby Bluetooth devices using your handset. Once connected, the T505 will remember your handset each time you power it on. Operation is simple – the call button answers and ends calls and the music button plays and pauses any streaming music, while two buttons on either side handle volume.

The most enticing feature of the T505 is its built-in FM transmitter. Even more convenient is a feature Motorola has dubbed StationFinder. Pressing the FM button on the rear of the T505 finds and announces the clearest FM station. Depending on what area you are in, this will constantly change. If your current station is dropping out or sounding distorted, simply press the button and tune to the station announced for clearer listening. We found this worked quite well and it is hugely convenient not to have to search for a clear FM station.

If your mobile phone supports A2DP Bluetooth streaming, the T505 can stream your music wirelessly to your car's FM stereo. You can control the music on your phone using the play/pause button on the front and the volume buttons on the side – the latter skips through tracks. The T505 can also stream both incoming and outgoing phone calls through your car stereo. This is hugely convenient as car speakers are usually much louder than the single speaker found on most handsfree speakerphones. For incoming calls, a female voice announces caller ID information if your phone supports this. If there is no caller ID, the voice will say the incoming phone number.

Quality of voice is passable, but not outstanding. Incoming voice is loud and clear for the most part, but our callers did note a lack of volume and clarity for outgoing voice. Like almost all of these units, you'll have to close your car windows in order to create the quietest environment possible. Do note that in terms of FM transmission for both music and calls, quality depends on the quality of your car stereo.

Motorola packages the T505 with an in-car charger, but no AC charger. The unit is rated at up to 18 hours talk-time and 14 days standby time.
