best way to set up equalizers on radio

[04XC90T6AWD]

what is the best way for me to set up the equalizers on a 2004 XC90 T6 AWD with a stock radio thats got a 6 disc in dash cd changer. I listen to mostly country i cant seem to get a setup that really shows the true quality of the Stereo.
Can i get some guidance please?

"pages" 180-183 will walk you through how to change the EQ settings and show you how to change the Dolby set up (if you have it).
As for where to set it for optimal listening, that is probably a user specific question, or at least one to ask on a "hi-fi" forum
