CR-V wrong time in the Navi, not correctable

Hello, since a long time again a post from me. On New Year’s Day I suddenly noticed on my original Honda Navi that the time is not right. Also the time remains the same with ignition from always, e.g. 18:00 clock. After I dared to transplant the step an original Honda Navi into my RE7 I thought first that something was wrong with the power supply. On Saturday then the Navi was expanded and the wiring checked. Everything was ok and frustrated again all assembled. Before all the works I had tried to manually set the clock in the Navi. No chance. Now the joke that I found only at the scouring of YouTube by chance: It is probably due to the software of the Navi itself. In a USA video a user has posted that Honda itself can or wants to fix this error only in the course of the year?? It also does not concern the CRV Navis special Querbeet Honda’s before 2015.
