Adjusting/tuning the CD/radio on new Yaris L

[rlrl]

Hello! I just bought a new 3 door Yaris L 4 weeks ago. Despite my reading the owners manual (which is well written but I cannot understand the CD player instructions for the life of me) I have not been able to crack the thing past pressing the "menu" button". I want to play around with the sound features (bass treble, etc) but I don't understand the instructions at all. I inquired on another auto website but they sent me to a board like this that is Toyota specific

this car replaces a 1992 Tercel which had a very simple system for tuning the cassette/radio sound, back before the days of computer tech

i mean i have a cellphone, a computer (obviously!) so i'm basically tech savvy but the instructions just escape me here

what do i do after i hit "menu"?

any Toyota sound system experts here? this is the basic CD player, no extras

thanks
