I have an iOS device connected into a dock to play some music (online radio stations, Spotify etc)
My question is if ti's possible to connect with another iOS device (iPhone, iPad) to this device in the dock and control/take over this device, so I can change music stations, adjust volume level and/or change songs?
I don't like to jailbreak, so only App Store apps or "standard" iOS 'tricks'.
Can this be done?
