Good afternoon,I just installed a parrot 3000 evolution and can recommend this site 100% Parrot Kits and Quick Connect Harnesses for Installation
you dont even have to push the button,just say "Phone" and then the persons name from your voice dialing,at least thats how my 8100 pearl works.
I bought a harness from them and the service and quality are outstanding,They have the Parrot line and a line of adaptor harnesses for most vehicles.they treated me fairly and quickly !! my two cents
