Maybe I am reading the owner's manual the wrong way, but what is the purpose of the round push btn. above the off-on volume ****. It has a triangle with a line under that on it's face. I understand mechanics of these cars, but this electronic feature whizzed right by!

If you are referring to the button on the left side of the radio above the volume ****...it is the on/off button. The **** you are calling the on/off/volume **** is only for the volume...at least in my Roadster Limited.

 

It also ejects the cd if you have one.

 

Radios with nav are different then the regular ones. Without nav the volume is the on/off.

 

it's a very hi tech feature... when you push it, a CD magically comes out.

 

But only if a CD has been put in first.
