NO VOLUME DISPLAY but looks like its working
 

im not sure what is going on with my radio but the Bluetooth loook like its works not sure if there is a mute bottom cause thats what it seems its like on?? if you could let me know where the mute is at? that would be great, but no display of volume is being turned up on knob or steering wheel. i put cd radio station but nothing. im not sure where to go what to do from here?? is it the amp a fuse or just the radio,:confused::o

Is this the original sound system?

The mute is suppose to mute the input signal. You should still be able to change volume via the steering wheel.

Depending on the sound system installed, there may be a 25A AMP fuse. Location in large engine compartment fuse/relay box.
