The following link will take you to the USPTO site to view the patent that ESCORT submitted before releasing the 9500ix. The engineering that went into this thing is absolutely mind boggling! It is interesting to note that ESCORT patented additional GPS/RD features (under this same patent ID) that could very well be incorporated into future ESCORT RD's.
This patent description will walk you step by step through the operational concepts of their GPS enabled Radar Detectors so that you can determine how these units "acquire" their Artificial Intelligence. This knowlege will help you to understand what your 9500ix is "thinking" while on duty...
Hope you enjoy reading this as much as I did
