I just finished my turbo install about 5 minutes ago, including the v-afc. However when I put in the key and turned it to the ignition setting, the v-afc's buttons lit up but the main menu did not show up. It's completely dark except the buttons which are glowing, I don't know what the hell is going on, if you can help me, please post.

 

same exact thing happened to me. recheck all your connections and make sure they are all done properly, then check the ground, make sure the unit is ground properly.

 

We double checked everything but we can't figure out why it's not turning completely on.
