308 double tape clock setting

Friends, there is a double screen multimedia system in my 308 2012 model vehicle, because the battery has changed, the time and date of the vehicle are gone, now I can't set it here, whoever I ask says you need to install an orj tape, but both there is no orj tape and they glued the screen with Japanese, one of the service said that the communication cable with the vehicle in those systems is not connected How can I do it when it's not plugged in? .hizliresim.com/ovld8bf.png" border="0" />

Hello. Org. I don't think you need tape. In my car, there is an info section on the screen that is installed later. The part where the battery voltage value is seen. I can set the tape from there. Display brand is necvox. There is definitely a similar part, it needs to be tinkered with a bit.
