After testing the iPhone 5 with the 30 pin adapter and the current cable from pioneer:
- Supports audio iPod output with ID3 data and album art
- Supports audio out apps (like Pandora)
- Supports controls (track change, thumb up, thumb down, next, etc)
- Will NOT support video iPod, video app, or Enhanced App Radio functions.
Without the 30 pin adapter, (using the included USB cable) all you can do is charge the phone on the X/F/Z Series.
It appears that the newer AVH Series units support direct USB connection.
