Playing music via bluetooth
I have 2012 750iAH.
I am using a iphone 4.
I can access the songs if the phone is in the cradle. But the music is not accessible if the phone is not in the cradle (I can still use the phone via bluetooth).
What can I do to access the songs via bluetooth without placing the phone in the cradle?
Also I am thinking of upgrading to iphone 5 -
a) I assume I would need a new cradle?
b)Can I access the itunes via bluetooth?
