Started a few days ago at ~ 350 miles - seemed to emanate from the center of the dash right below the windshield. It turned out to be the visor over my side not being latched!

On another note, took her out on the highway today and was amazed how quickly she went from 70 to 100 mph - and I didn't even floor it! No wonder you guys get speeding tickets. The wife says I better put some money aside for future fines..

70-100... hehehe... just wait, and take you're wife's advice.
