One additional data point: Bluetooth MAP function appears to be selectively implemented by phone manufacturers that claim to implement it.
I tested the function of a VZW edition Samsung Galaxy S III (that VZW claims supports MAP on their website). After pairing was finished and MAP connection was implemented between the GS III and the car (phone asked if I wanted to activate MAP, I clicked the yes box), only SMS messages would display. Contacts on the GS III were transferred to the car with no problem. But no e-mail. I didn't spend too much time trying to mess around because I didn't want to risk breaking the integration with the BB Bold 9930.
Curiosity has set in and I am seeing who I can borrow an iPhone 5 from to see if it works with the car.
As I posted earlier, if MAP function is important, make sure it works for the exact environment you are wanting it to work with.
