SPECIFICATIONS:

• Provides 12-volt accessory power
• Allows for the installation of aftermarket radio using existing factory wiring and connectors

ADD-ON:

• When a vehicle doesn't have sound or the sound is intermittent after installation, it is due to a malfunction of the wake-up signal in one of the components of the MOST ring. With this ADD-ON the wake-up signal is completely bypassed, reducing troubleshoot and installation time. 
• If after the installation sound is working correctly and there is no need for the wake-up signal bypass, the ADD-ON portion can be returned for a refund within the normal 30-day return window.
