Well, I installed a Parrot CK3000 in my bosses car today and discovered later that the iPhone is no longer listed as a supported phone on the Parrot support page for the CK3000... I'm guessing this is because downloading the contacts from the iPhone doesn't work.
Oh well, My Boss likes it anyway.
I on the other hand, I now know that the best choice for My car will be the CK3100. Apparently form other posts I have read, it can download the contacts.
