Noobie!! I have a z110bt that someone gave me. I updated to a z120bt w 2013 maps. (Paid for) I am reading all these threads about updating to a z140 so I can use my iPhone 5. If I am reading correctly it can be done. Can someone help orzo point me in the rite direction or I will sell it and buy another app radio 3. It worked so well. I got talked into this radio ut if it isn't capable to do what I want then I will give it back n buy something that will. Thank u to anyone that can help
