Dear All , I have installed Parrot MKI 9200 in to my 2011 GP Emotion with a Delphi HU. I will highly recommend this product to all Emotion users if they want a Bluetooth/SDCARD/USB/AUX option in their car. I have not opted to change the HU as this HU sounds quite nice in my present setup ( with Blaupunkt THA475 and Renegade 300 W Amp). Yes there are few HU available for GP for around 400$ which is too expensive and sound quality of these are always doubtful. Parrot MKI9200 got integrated with existing wire harness of GP ( you need to swap a wire in power connector) without any problem. Sound quality of this system is even better than OEM HU.DSP and equalizer are of goo quality and sound quality is excellent. This unit has its own AMP and does not use HU's AMP for powering speakers. conversation with Bluetooth is crystal clear and integration with android phone is smooth. Most of the voice commands works. when you try calling someone by name, well I am afraid to say, this unit is not perfect, but you can dial by manual method without any problems.
