RP5-GM61, GM6A-RST: No audio in Bose-equipped vehicles

In Bose-equipped vehicles, all audio components are connected in a loop. If an audio component is missing, you will not have sound. For this reason, the RP5-GM51 / GM6A-RST provides jumpers to remove unnecessary audio components. The unnecessary components are the external CD drive and DVD drive. Two jumpers are provided depending on which external drive you have. You will only use one of the two jumpers. Discard the one that doesn’t plug in.
