Sound Output Configuration

The method for transmitting sound to the original car system varies by NTG version:

• NTG 4.0 and NTG 4.5: Transmit sound via AUX or AMI. If your car has AMI, prioritize AMI audio cable. If no AMI, use the AUX input. You may need to manually switch to AUX mode in the NTG menu.
• NTG 5.0/5.5: Needs to be connected to the USB of the original driver's armbox to have Android sound. Plug the audio out on the ISO power cord into the 3.5mm jack of the USBAUX Box, then plug the USB jack into the USB on top of the car's armrest box.

Attention: If there is no AUX or AMI on your car (for NTG 4.0/4.5), you will need to add an FM transmitter to produce audio. However, the sound quality will not be as good as AUX or AMI. Please acknowledge this before ordering.
