First, CM10 Nightlies has the needed update to Bluetooth Message Access Protocol (MAP) for the MyTouch to properly read text messages as they come in. (whomever did that, thank you!)
Second, it was bugging me that the Nexus wouldn't push the full contact card, to include the contact photo, so I set out to find a way to do this. Getwiththeprogram over on the Sync Owner to Owner forum found this neat little program called Bluetooth File Transfer which has the ability to push contacts, INCLUDING pictures, to the MyFord Touch system. Below is the link. Simply remove your current phone book from the MyFord Touch, disconnect the phone from the system. Then, manually add the phone in the bluetooth settings instead of having it open for other devices to connect, where you put a code in both the phone and then on the MyFord Touch. Once connected, both the Bluetooth File Transfer software and the MyFord Touch software will see each other. Last step, on the bluetooth file software, goto options, more, then send contacts, and select which ones you want to send (all, some, whatever). On the myford touch, select ADD CONTACTS (manually again) and then have the phone push the contacts. You should see the car updating contacts, one by one. The screen will go away, but it's not done, wait for it to come back and say it's complete.
That's it... and to be honest, that took a lot of digging to find, it's not documented very well anywhere.
If you get stuck, just let me know, I might be able to help.
