There are two power feeds to the radio, one is battery power at all times and the other is power with the ignition on. May sure all your connections are correct. Wiring diagrams are available from The standard colors are orange for continues battery power and yellow for ignition on. If there is no power on one or both of those wires you will need to backtrack the circuit to find out where the problem is.
