i've had my '13 G37S for a week now and i'm still trying to figure out the best way to navigate and the audito controls. i'm havnig an issue with the bluetooth and my iPhone. i've paired it and it's connected to the car but sometimes when i get in the car and cahnge the source to bluetooth i can't play my music frrom the touchscreen or switch tracks with the steering wheel controls - sometimes i can. when i can't use the touchscreen i get an error message that states:

Ryan's iPhone is not possible with this device

even though i get this error my music still plays and i can control it from the phone.

what's up with that?
