This kit merges audio and chime signals like the factory system. When turn signals are on, the audio volume is lowered so chimes can be heard clearly. This applies to all chimes. If chimes are too quiet, update the PAC interface module to increase the chime volume.
Applicable Part Numbers: GM6A-RST, SRK-GM14HX, & SRX-GM14128
