Cobalt Link+ is a flexible, cross-platform screen sharing and remote control solution. This application enables the remote control of your iPhone or iPad from a compatible display running Cobalt Link+ viewer software. This makes it possible to use apps and other features on the device in a dedicated setting, for example via a vehicle's touch screen whilst parked, or on the move. This may include in-car navigation apps, music streaming, making or receiving phone calls, and even playing video games when in a safe location. Communication between the display device and the mobile device may be conducted either wirelessly or via USB cable. Simply pairing them over Bluetooth is usually the first stage, or plugging a compatible cable from the display into your devices charging port. You can then access all your favourite apps in a safe, convenient and enjoyable way!
