I have a weird problem. I have my phone mounted in a cradle which sits on that flat ledge where the nav/multi-info display and information display are. Today, a clip from the cradle broke off and -- in a "one in a million shot" -- fell into the left most center vent (to the left of the Hazards button). Here's where I start to worry. Where will that clip end up? Are there filters along the way that will catch this and keep it from getting into the engine? Or does the vent open into the engine? Is there any way I can access the vent and extract this piece? This is a 2012 Mazda3 5dr iGT.
