PLEASE NOTE: These settings can be adjusted with the module installed in the vehicle, or on the bench. However, it is 

recommended to make the adjustments with the module installed, and the factory radio on, so that the changes can be 

heard.

Minimum Volume Level -  

This allows you to set the minimum volume level of the factory radio (factory radio volume level 1).

Chime Volume Level - 

This allows you to set the volume of the AP4 chimes (ie: park sensors).

Chimes Enabled - 

This allows you to enable / disable AP4 chimes (ie: park sensors). This is used when mixing factory and 

aftermarket speakers.

3 Band EQ Enabled -

Bass / Mid / Treble Freq / Q Factor -

 This allows you to set the center frequency that will be adjusted when setting the 3 band
