[QUOTE="ahole-ic, post: 6714636, member: 619324"] You need a DC voltage meter. You need to check your voltages in the back of your head unit. Put the positive probe on the yellow wire and negative on the black. You should read 12v or more. Move the positive probe to the red wire. You should read 12v or more also with the key in the on position. If either of these is not true, you need to replace that fuse. If it's the red wire and it STILL have voltage after you've made sure the fuse was good, you need to replace the relay for it. If that STILL doesn't work, you need to replace your head unit because you killed it. [/QUOTE]
