I have a 2000 zx2 with the am/fm/tape/cd factory radio and recently the radio has failed to operate. The cd works but when I push the am/fm button the faceplate goes blank and no responce from the radio. The unit is still powered on though and I can select the cd player and it plays with all of the features (fade/balance/bass etc) I've checked the fuses and I don't know if there is a seperate fuse just for the radio itself. I'm thinkin not and I need to find a replacement radio. Any suggestions?
