Works very well. Better than the bluetooth that came with my stereo that I put in to my previous vehicle. It is clear on both ends with simple features.My cellphone is not compatible with this unit so I cannot use the extended features like voice command; however, it is still capable of receiving and making calls. That is all I really needed.A very capable unit that makes and receives calls with a clear reception on both ends. In order to make sense of the wiring one must use the instructions from the Parrot along with the one from the wiring harness . The whole project seemed a bit intimidating at first but as I started following the install instructions things got easier. You just need to make sure that you take it one step at a time and double check your connections. The matching vehicle wiring harness is an absolute must. I would not recommend anyone to try it without unless you are a professional installer. I installed mine on a 2011 Pathfinder and it works as promised. I had absolutely no problems and it came on the first time I started the car.
