Summary: Don't get me wrong the price is great and it works well with your phone for calls but thats it. The SD card wont read the files (mp3) and cancels out after 30 seconds, if you get a message or something while driving it cuts out and tries to sync music from your phone, even if you have an Iphone directly plugged in though most Bluetooth devices seem to do this.
Conclusion: The Parrot MKi9200 will not work well with the Lockpick GMX550 even after contacting Lockpick about it (they said to get a Parrot but did not say which one). Trust me, don't waist your money If you want this as a combo with the GMX550. It Looks good and I love the features. Shame it did not work well with what I have.
Summary: I was expecting greater things given the price of this kit. It was the most expensive one Halfords did and whilst it does the job, the quality of calls is nowhere near as good as I had hoped. Yes it does the other bits, like playing music, voice recognition etc, but everyone really wants the kit for making calls and in this respect it was distinctly average unfortunately.
Conclusion: Fair audio quality no matter where the mic is positioned. Can't compete with the better Bluetooth headpieces. Fairly buggy with iPhone. For example, we have to plug in our phones and then unplug and replug to get the audio to work. The amplifier should be stronger. Oh highways it's barely enough. This is the best of the worst. In otherwords, there aren't any other better integrated options but this is only average at best.
Summary: The problems I have is the music player and voice activation. I have had to update the software twice since buying this to get around the problem of an album suddenly stopping mid track. Been told its due to issues with Iphone 4.1 software. Sometimes it reboots itself sometimes it doesn't. The bad thing being it knocks the radio out too so I have nothing to listen to.
