Stolen: Garmin Edge 500 2011

My Garmin Edge 500 GPS unit was stolen off my bike, while my bike was in transition during the Ironman Durban 70.3 event. The theft took place sometime between when I finished the cycle leg of the race (+-10:30am) and before I collect my bike after the race (+-5pm).  If anyone sees a very cheap Garmin Edge 500 for sale please check the serial number and contact me.  (Luckily no stolen bike but I'm not sure where else to put such a notice).
