I have installed the Mki9100 is 2 of our cars with out built in bluetooth and they work great. Phone sound quality is superb. It rivals any car that has bluetooth already built in. I have had 2 older generations parrots previously also. It is so convenient to have in your car. All cars should have integrated bluetooth standard. Once you turn your car on it links automatically. You can stream all audio directly from the iphone. Siri works as well with the parrot, by pressing the play button on the remote.
Are you installing it yourself or at a car audio place?
