Does anyone know what's the purpose of the "Set" button on the left side of the steering wheel - next to the volume buttons? All I know is it screws up the volume level of my stereo and I can't raise it afterwards.

i believe it is for "set"ting the level of the radio if you needed to quickly reduce the volume i.e. getting a call on your cell phone. set the volume where you would like the radio to be and hold the set button down until it beeps. the next time you push the set button the radio will go down to that level. to increase the volume use the **** or volume buttons on the steering wheel

 

DPR supra is correct. I set it to '0', as a mute.

 

Thats good to know, I always just turn the radio off when I get a call. I found an open connector under the center console. I wonder if this connects to the optional phone tie in. Maybe this connector will allow the mute function as well. Could be of help to the XM and Sirius fans.

 

PRONTO!!!!! get to it Sherlock, as I'm getting my car in Feb and want to have Sirius Sat. installed in it.

 

oh man, that's what i get for not finished reading the whole manual yet... damn,,,, find the time find the time....

anyway, the connector below the center console? where exactly? if it's under the steering wheel colume, then that's for the diagnostic computer. if there is another one i would love to know where too

 

super helpful! I've needed a MUTE button ~ Thank You!

 

This loose connection is for the mayday cell phone that was wiring installed for equipping a cell phone it is called the mayday
