+1 Check the wires. If your installer followed the latest manual, the installation kit uses wire taps (really flimsy and cheap) for the power wires (ground and +) to tap into the CAS Unit which is found under the driver side dash (foot well cover area). If you remove the foot well cover underneath the steering column, you can check if the power wires are connected/tapped properly to the 1 pin and 12 pin wires on the connector going into the CAS Unit. Now, if your installer used a different power source, I don't know where you should look.

Hope that helps.
