all right first you've got to...well... start up the car because if you don't start up the car then you're going to lose the settings on here and right now is looks like it's set up to 87.5 and its going on the first track you can press this right button right here to go to track two (2) track three (3)...track four (4) so on and so forth and you can go back a track here if you press and hold on the right-most button, that gives you Volume so it goes 01 to 16 if I press the "A" button as you can see that brings your Channel down by point... ...you know...one, .2, .3 increments do the "B" it goes up uh...right now you can barely see this little...uh... this little SD card in there, in the back kinda goes upside-down instead of right-side up so I'm gonna plug it back in and as you see on my stereo I've got to have it turned to the right station, so 97.5 is what I've got it on on my remote
