I am installing my F700BT and using a GMOS wiring harness. The speaker connectors on the GMOS are RCA connectors, my question is can I just cut the connectors off and splice the speaker connections on the nav since all that is there is wire leads?

 

I also have a BLUE/WHITE wire (from GMOS harness) they say to connect to the AMP turn on wire on the F700 and I can't identify which wire that is on the nav.

 

Last question has to do with a BROWN wire from the GMOS that they say to connect to the mute wire on the F700, there again, I can't locate the mute wire.

 

I would appreciate any help anyone can provide, and I am sorry if these are simple questions but this ia all new to me.

 

Thanks.
