Question: Why MongoosePro II can support GM GDS2 & Tech2Win?
Answer: GDS2 & Tech2Win can support different VCIs (Vehicle Communication Interface) based on D-PDU standard, such  as GM MDI, Bosch MVCI, Drewtech CarDAQ plus, Drewtech MongoosePro GM II..., GDS2 can recognize the drivers of interface installed, so that the user can select the interace in the application, and make GDS2 to communicate with the ECUs of vehicle.

Question: Why we say MongoosePro is the best choice for technicians?
Answer: Technician can use GM MDI, Bosch MVCI, Drewtech CarDAQ plus, Drewtech MongoosePro GM to work with GM dealer diagnostic application GDS2, but MongoosePro is the cheapest interface compared with others, the user can save money, moreover the clean design of MongoosePro GM II with electronics protected by cable is a maintenance free solution that allows user to avoid frequent damages on main diagnostic cable and the commuincation port of interface.
