Well, I don't know how they would plan on installing this, but this unit has Bluetooth music streaming. But since your car does not have Aux In capability I can't see how they would get it into your head unit in order to play the music. I hope not by using an RF Modulator which is real low quality.
Also, where would they put this big honking screen? I am not a big fan of Bluetooth aftermarket units with a screen, if it isn't a factory system then I can just look at the screen on my phone. Why have two? Plus how are the going to get voice into the car system? I am real curious what the install plan would be! It is hard for me to judge without knowing more.
If you decide to stick with Parrot perhaps a lesser unit without the A2DP streaming would be a better fit. I personally am a fan of a unit that is a bit older but can still be bought, and very cheaply I might add, on Ebay. The Motorola HF850, it is a hardwired solution, has an external microphone AND speaker. Turns on and off with the car (if you wire it that way), plus sounds great on phone calls. I used this model for 8 years in every company car over that time. The Motorola has a controller pad that you can mount unobtrusively for answering and ending calls, but no external screen.
