The LED light on the BLUECUBE6+ Hide-Away Stereo tells you if the unit is power on/off.
If your LED light is not on, but the unit is working fine, then the LED light is likely dead.
If the LED light is not on, and the unit is not function at all, try to unplug the harness and any power source going to the unit. Let the unit sit for 15-30 minutes and then reconnect it to see if your problem is solved.
If after you have tried everything, and it is still not working, please contact our Support team at [email protected] for further assistance.
