This is my solution to an issue I've seen reported several times, but never seen an easy answer too.
I have just fitted an aftermarket head unit in my Boxer PVC. The original headunit was the VP2 Sat Nav system, and with this option installed from the factory the time and date are set from the touchscreen. Once it is removed from the van, there is no way to change the dashboard clock.
In vans without the Sat Nav from factory, the time and date can be set from the MODE menu button by the drivers knee, but this menu option is not available with the touch screen - it just doesn't appear in the list when you press the MODE button.
This is the original unit:
Things I have tried that did not work:
I've also read there is an Android app called AlfaOBD that allows more settings to be changed that the Torque app I have used, but I've not tried it.
The final option that I have read about is simply to re-fit the old headunit whenever the time needs to be changed. Although this will work, it's a right PITA and not really practical.
My solution is a slightly more convenient version of this last option. I have soldered a cable that connects the CANBUS and power pins from the back of the original headunit to an OBD plug - I can then connect the old stereo to the OBD port twice a year to change the time settings. Between times it can sit on a shelf in the garage until I need it.
Here it is in use:
Here is the OBD pin connections:
Pin 16 - +12V
Pin 4 - GND
Pin 1 - CAN (+)
Pin 9 - CAN (-)
And at the headunit end:
Pin 2- CAN(+)
Pin 12 - CAN(-)
Pin 43 - GND
Pin 44 - +12V
I ran into problems initially because the OBD standard is for CANBUS to be on pins 6 and 14 - when I connected the stereo this way I got a load of dashboard warnings. Turns out 6 & 14 is the high-speed CANBUS, and the stereo on the low-speed system, which for the Boxer / Ducato / Relay is pins 1&9.
Anyway - the OBD plug cost me a few quid from ebay and I had the wire and connectors already, so I'm happy with this as a workable solution.

Things I have tried that did not work:
- Removing the original head unit, and hoping the menu option will magically appear - NO
- Disconnecting the battery at exactly 12:00 - NO, the display just flashes a blank time
- Entering the Engineering Menu (hold down Radio, Menu, Browser) on the original headunit and looking for an option to select - NO
- Using a bluetooth OBD dongle & the Android Torque app to look for an option to set the system time - NO, this is not possible with this app.
- Getting an auto-locksmith to check his diagnostic system for an option when I had a new key cut - NO, he could see the body config settings, but his system couldn't change anything.
