[wildtsunami21]

hey guys, i have been looking around, and i dont know why my headunit and cd changer wont work.

i have nav, and the push button to power the stereo on, i pushed it and nothin power on, i checked the fuses already. i tried to take out the cd magazine, but it wont come out either. it seems like there is a lost power source to the stereo system or something, but idk.
the nav is still power on and working fine, but the stereo and cd changer is not working.

any inputs?

thanks,
