If you replace, the charger/connector and use an iPhone 6, iPad etc.., you may want the 2.1amp/12watt adapter. The iPhone 6 battery is designed to accept a higher amp. The current setup in the 370 is the smaller amp designed for the smaller battery's used in the iPhone 5 and previous. I could not get it to play and charge, so I just got a cigaret lighter USB with the larger amps and forgot about it.
I talked to Nissan about it. They agreed they are behind the times on this port, but told me it would void my warranty if I upgraded. Lol
