Installation and configuration

The back is as important as the front

LX navigation strives to develop easy to use as well as easy to install instruments. To provide clear functions and actions, we mark every button or rotary knob.

The same applies to the back of the device, where we mark each port. The installation and wiring should not take more than 30 minutes of your time.
