I just tested the compatibility of my Pearl with the Ford Sync and the XBOX 360.
The Ford SYNC is their new cell phone/MP3 connectivity device. I plugged it into the SYNC system on both a Focus and Milan and it worked! I could use the voice commands to make and receive calls over Bluetooth, and the MP3 interface (via USB) to read my MP3's in mass storage mode and I could select and play them again with voice commands.

. Sweet cheap add on; I ordered it in my daughters and wife cars.
While I was curious, I plugged my Pearl into the XBOX 360 and again it worked. I could play MP3's, see pictures (also with the slideshow option), play videos (unfortunately only MP4's I converted from YouTube, AVI's didn't work.
