Volume issues with a hdzoom hdz300
I just installed an hd-zoom HDZ300 on my motorcycle everything seems to be working well except the volume . I can hear the radio but I can't increase or decrease the volume..there are no other radio/player devices installed on my bike..only some speakers from an old radio installation..they worked fine with the old radio.
So do I need more equipment, like an amp, or is there some menu for volume that I just missed??? Or am I screwed and these must be installed with an existing radio system??
SORRY ABOUT DOUBLE POST DIDN'T SEE THAT I HAD TO WAIT FOR APPROVAL.THOUGHT MY FIRST ONE DIDN'T POST FOR SOME REASON..CAN SOMEONE REMOVE ONE OF THESE???
