I looked at the compatibility list and I agree, it only shows like 3 phones that no one has that are compatible but I see others saying they have text to speech messaging so I think that list is outdated. Also, there's a lot of talk about an update that provides more functions after installed. I wish they had not removed the hard drive function. I guess I'll download my playlists to a usb drive. I can use the SD card because I have to have the Nav card inserted in there. What's with that anyway? I thought the Nav system would be downloaded into the system memory, not on a darn SD card.
