On D-Day 6th June 1944 why didn't the German Navy come to Normandy to fight the Allied naval forces?

The German surface fleet was no longer a significant force by then. Most of their heavy ships had been sunk and the remainder were confined to ports on Germany's North Sea coast. Allied air supremacy and sea power made it impossible for Germay's few remining ships to sally forth. Allied air power also denied Germany use of the French ports. Thus, even if their ships had wanted to leave port, they were much too far away to do anything about it.
