According to Trimble, the oldest version of GPScorrect to work with ArcPad 8 is 2.42. I have been unable to determine the oldest version of GPScorrect to work with ArcPad 10. I am assuming (as the case has always been) that some versions will not be supported with newer ArcPad versions. We currently have 7 units running 2.42 and will most likely need to upgrade to 3.02 (latest version to work with ProXR). Of course if ArcPad 10 is not compatible with GPScorrect 3.02, we are SOL. Any input and any links to documentation is greatly appreciated.
