Hi Jerry,
Thanks for your questions on the costs of integrating GeoEvent Processor into a project solution. Questions such as license costs and quotes for Professional Services engagements are best handled by a Customer Service Representative or Sales Representative. If you are affiliated with the Esri EPN your Technical Advisor can also help with obtaining quotes. An Esri Sales Representative might be able to help you identify commercial providers for in-vehicle GPS units, but many of the providers are Esri partners so we cannot recommend one provider over another; so this is not an area which Esri will likely be able to provide you a cost estimate. Again, thanks Jerry.
