We love anything that comes a-packin' no muss, no fuss technology -- even more so when you can install it in a few seconds and don't need a toolkit to get the job done. Parrot's newest Bluetooth carkit, the PMK5800 consists of a single part which plugs directly into your car's 12V accessory socket or cigarette lighter. Using a built in FM transmitter (a la iTrip), the set will stream tunes via A2DP from your handset or your voice calls to your car's stereo deck to give you that auto-filling sound you love. When the phone rings, just hitting the FM preset you configure for the PMK5800 will automatically answer it and mute your music. While not an embedded kit, it packs all the goodies you would expect like DSP, echo and noise cancellation, full duplex sound, and voice recognition all in something that can go from car to car without effort. Look for these to land sometime this summer for about $120.
