Radio - No Power

I've got a 2006 Grand Caravan. I had the interior cleaned by a detailer today. On the way home after picking it up I noticed that the radio had no power. I've checked all the fuses and find nothing wrong. Everything else on the van seems to work.

Is there a switch somewhere that the guy cleaning the van may have tripped??? Anyone have any suggestions?

So far I've checked all fuses, disconnected/reconnected the battery, search for disconnected wires, etc... Nothing!

Any suggestions would be appreciated. Tomorrow I'll be taking out the radio to check for power at the plug.
