i've unplugged my headunit to hook up my remote wire for my amp..when i plugged everything back in i realized that the display screen doesn't show anything...time, temp, track listk, etc. the buttons on the head unit and the temp controls doesnt work either...the only thing that works is the eject button..everything has power.the lights light up and everything. its just the buttons and the temp controls and the display screen not working..i don know whats wrong with it..i've checked all the fuses tried everything i can think of and still nothin..any help would be appreciative..thanx

 

Its probly the fuse has blown try lookinh in the fuse bow inside the car and check them out. this happen to me few months again when i accidently touch the power cable together when fixing my amp

 

Especially if you are getting main power just the display is not working I almost bet it has to a fuse. Just go one by one and try it. Sounds tedious but that way you will know for sure if it is or is not a fuse.

 

unplug ur battery and reset it. THis happened to me, but i did nothing at all. just nothing showed up on my display, but the music worked. i brought my car to mazda they just reseted the system. try that, thats what they told me. they unplugged the battery and reset the system.

 

I've checked all the fuses in the engine bay and on the driver side compartment with the test light..all the fuses seems to be working fine..i was thinkin maybe its the internal head unit fuse..but when i took the head unit apart i dont see any kind of fuses..i asked one of my employees about it and he said it could be like a wire fuse not them little square fuses..i've unplugged the battery, did almost everything to it and still it doesnt work..how do you reset the system???i havent tried that yet..thanx for all your help..
