Does the HU work if you connect it straight to the battery? If it doesn't maybe there is a fuse inside the HU that blew.

MIND_L which wires do you connect to which battery terminals? Never heard that before.

Anyway, Check all your wires, make sure properly connected and no wires touching (if you used electrical tape). My problem was loose wire! Thats if your lucky, probably blew fuse inside head unit though..

twist the red and yellow together and connect to the + on the battery, the black wire goes onto the - on the battery

Which fuse blew? on the back of the radio, or in your cars fusebox? If it is in fusebox, might be another problem besides radio.

look man......you cant blow a fuse in the vehicle if you dont blow the one in the back of the HU first...check that one.

Listen supraman I guess you have no idea about the flow of current. If he touched the wire from the fuse box to a ground it would blow the fuse in the fuse box and not the one on the HU. If the short is after that connection then he could have blown both at the same time.

There is no reason to come on here and have an attitude with people who are asking for help.

But back to the problem. Check all the fuses in your fuse box, and the ones on the back of the radio. Also check to make sure you ant is hooked up and is getting a good signal. Some HU do not work well and will not power on without that hooked up.
