I hate to say this, but the fact that it was professionally installed doesnt mean much. Did you actually check all the connections yourself? One of the wires may be loose where the wires go into the docking connector. The wires in the connector pull out really easily. If that is the case, either fix it or email support and they will send you a new wiring harness. Are any of the wires in the dash exposed and touching the metal inside the dash? Look inside the docking bay from the front and make sure all the gold contacts are pulled all the way forward to the front of the connector. I also read that someone had a miswired ISO connector a while back, but havent heard of anyone else having the same problem since.
