I was trying to get my radio display to show Scion in Japanese.... They didn't give me an Audio owners guide with my new car.... what is the "A" and "M" buttons???
AM-FM ? Aux ? Mute ? I couldn't get the instructions to work... help !!!
Feel free to email me privately on this if ya like code3mmc@juno.com Mike in KY

 

M is mute. A is for the Audio Controls. Such as Bass, Treble, Balance...so on. You get the picture. You can press those, don't worry :D They won't make the radio blow up....well, only if you want to blow the speakers :D

 

if you mean the M on the sterring wheel controls that is the mode button to change from cd-aux-am-fm-xm whatever u using!!! and the a as lil_blue_star said for the audio controls....
