I downloaded and made the 3970 CD and installed without any trouble. Checked immediately if now the PersonalPOI would work. YES it does. Got Europe Blitzer (Radar) from NavyFriends site and converted via VW NavyCompanion into RNS database format and copied onto SD card. The RNS 510 (actually COLUMBUS in my Skoda Super-II) accepted it and uploaded the POIs into the Navy. Did not have tim to do any test because I am stuck to bed now with a herniated disk (sh***).
