LotVision is a free vehicle tracking system by Manheim that serves buyers, sellers, and transporters at Manheim auction locations. It locates vehicles on auction lots using small tracking devices, providing real-time positioning accurate within ten feet. Users search vehicles by VIN or work order number via web browser or mobile app. The system includes diagnostic trouble code information for most vehicles on lots, displaying generic SAE-standardized codes with descriptions and timestamps. Tracking devices remain installed until Manheim staff removes them at vehicle pickup.
