I have the adapter to connect my iPad 4 on my digital Docking Station Onkyo ND-S1 brought me to including times to watch videos on my TV next to music.
Positives: Very good workmanship. Charging and digital music enjoyment works perfectly.
Disadvantage: Video output is no longer supported. Why unfortunately was the friendly staff at the store was not answered (especially looked after).
For me it unusable and goes back. Who "only" want to listen to music and charge your device, is hereby well advised.
