Dose anyone know if there is any software updates for the OEM NAV systems sold in Speed3's, I have an 07speed.. and when i use the navigation system.. not able to locate stores like home depot, costco.... think the maps need updating but don't know where to get updates from. The parts department and service rep at a local dealership out here in AZ.. said they have no idea on how to get updates for the system... any help is appreciated. TIA
