Thanks, Jim. Good thoughts for me to investigate.
I hadn't really thought about whether the Parrot would interface with the Nav screen. And if it doesn't then that question is a non-issue. I noticed a thread earlier where a member had posted a detailed review of the Parrot and he used the external speaker so that he wasn't needing to customize the whole existing audio system. Maybe that's my answer.
So maybe Vais for it's iPod compatibility and then something else (whenever) for bluetooth if I choose.
If the thread you are referring to was by "Blake918", he did not connect his Parrot MKi9100 to his 99 LS400 audio system so that the Parrot's iPod/aux/USB function could be used to play music through the car's speakers -- only through the single mono Parrot speaker. I think he was mainly looking for the the Bluetooth function of the Parrot since it works well with iPhone. I think he hardwired the Parrot's power, ground and mute wires to his 99 LS similar to how he installed the Nokia CARK-91H phone kit he had on his 95-97 LS had and I still have in our cars. (Thanks again, Blake, for sending me all those CARK-91 parts! -- wife's still using the replacement cradle you sent.)
Maybe you could find a Parrot dealer/installer who could tell you if the Parrot MKi9000 can interface with the ES nav screen -- I'd be surprised (no, amazed) if it did. There are some cool Youtube videos showing how people installed Parrot Bluetooth kits into their mostly European (mainly VW) cars using interface harnesses that allowed the use of existing steering wheel controls and the car's information display. One of the Youtube videos noted that the Parrot MKi9100 can not connect to a Bluetooth phone while a USB memory device is plugged into the Parrot.
Usually, where there is a will, there is way.
