Android 4.0.x and BMW Bluetooth

[Gadgets4U]

I'm new to the BMW Bluetooth systems as my previous ride an 09, X3 didn't have it, so I installed Parrot MKi9200 & UNIKA interface. Now I'm in a '09 X5 with Bluetooth as part of the iDrive, I've found that for some reason the "+" sign in front of the numbers in my phones contacts doesn't get transferred to the iDrives phone book. I use the + sign as I travel internationally a fair bit.
I seem to remember that the BMW sales reps iPhone worked and transferred the + sign when he demonstrated the car to me.
Has anyone else had this issue and found a work around or fix?
