NG4 (Citroën C5 X7) Date does not change to next day, time works correctly

So, is your radio finally working properly or not? First, you wrote that you don't have the module and that disabling it will fix the problem, and now you're saying that you need to find its power supply...

I disabled this module and it didn't help. At midnight the date remained the same.

You are right, that i make things confusing, let me explain something. In the past I had no problem with the date.
But sinds about a month I have installed the dash cam with parking mode, this is the reason, that the car switch to ecomode a short time after I switched off the engine.
Sinds then the date doesn't change anymore.
So to check if the ecomode is the problem, I changed the time in the middle of the day to 23:55 and keep the engine running so he won't switched to the ecomode, when the time changes to 00:00, the date also changes to the next day.
Again sorry for some misunderstanding.

I also never had a problem with the date in the past. I have this car for 5 years and the problem started about 2 months ago. I dont have a problem with eco mode, I have new 1 year battery and you my firend dont have this services module so this is the wrong way. The date doesn't change on its own, only in the middle of the night.

I have the same problem with my c5 (X7) since the new year. The date reset to 1/1/200? sometime around Jan 1 and now the time still works perfectly but the date remains where it is and does not increase. Be interesting to see if it’s a software issue.

It's not a software issue. I bought NG4 unit from 2010 and date was still not moving forward. Next time I bought Ng4 unit from 2011 and now date is working! But now I have other problem, the radio control roller on the steering wheel stopped working with newer radio....
