Mini-jack RX Bluetooth Music Receiver

I got this to integrate my Android (Droid 2) phone with my car. My car already has Bluetooth phone integration, but does not support A2DP (music over Bluetooth). This tiny little device was the perfect answer I was looking for. With this device in place, I retain all Bluetooth phone functionality provided by my car-stereo and in addition listen to music from my phone through the stereo.Pairing it to the phone was a simple process and only has to be done once following the procedure in the manual.The device charges via a mini-USB jack. It was a great fit for my car as it already has a standard USB outlet. So I could plug in the device without having an ugly cigarette lighter adapter. I plugged the audio out patch cable from this device into the AUX input for the car stereo. I leave my car stereo set to the AUX input.Although the device has rechargeable batteries, I never use it because it is constantly hooked up to my switched USB outlet in my car. This simplifies the use of this device. Here is the routine: When I get into the car, when the ignition comes on, the device wakes up. All I have to do is to touch the button on the device for 2 secs to reconnect to the phone and I have audio streaming from my phone from where I left off. This is great especially when you listen to podcasts and want to continue from where you left off. When I am getting out of the car, I just have to briefly push the button on the device to pause the music on the phone.When a phone call comes in during the ride, the phone automatically suspends the music and I get notification of the number on the car-stereo display. Once again this is not the functionality of this device, but the phone integration feature of my car stereo. I then follow my usual routine to dispose off the phone call. The music resumes shortly afterward.The great advantage is the hidden features for audio control that other reviewers have mentioned.Short Push: Pause/Play musicLongish Push: Restart current track. (CAUTION:An extra long push will turn the device on/off)Double click/Push: Move to the next track.The music quality is good. However, since I listen mostly podcasts involving normal speech, it is not a major concern. My car stereo has independent level adjustments for each input. So I was able to adjust the AUX input levels to match my radio levels and I do not have to fiddle with the volume whenever I change inputs (say to an AM radio station to catch traffic info). This may be important because if the volume is turned up too high, you may hear a hum being picked up from electronic interference as well as thumping when the device is turned on and off.The main disadvantages include the obnoxiously flashing bright lights on the button (that can be fixed by a simple black tape). The placement of the charger input and the audio jack on the device (on either side of it) makes mounting a little tricky. I wish they were on one side to allow for a cleaner mount. I also had a minor issue where there will be stuttering of music played. I found out if I disabled Wi-Fi on the phone, it went away. I do not need Wi-Fi when I am on the move.If the above irritants are fixed and if the device had dedicated media control buttons (including rewind/fast-forward within a track) it would make it THE perfect device for me!
