Installing a DDX616 in a 10. I have everything for the install and know 99% of the wiring but there is a brown mute wire. Do I need to hook this up or is this for older seperate BT modules? I assume the built in BT will do the muting and whatnot but wanted to get confirmation that I dont need to hook up.

Also on my XVSI 5520 harness there is a pink wire with a connector labled phone mute, do I need to do anything with this? I again wouldnt think so but want confirmation.

Thanks in advance.
