P70 with S2 FW Update and System Detection

[JYLC48]

Helllo!

I have an older S2 course computer with a new P70 control head. The steering system is hydraulic (type 1).

ST50 generation Seatalk instruments are also connected at the S2: Depth Sounder, Wind speed/direction, NavData.

The P70 functions correctly in that it controls the heading of the boat based on the S2 compass reading. It also correctly repeats the output of the other instruments (depth, wind speed, SOG, etc). I have not tested Wind vane steering yet, nor NMEA/GPS based autopilot function.

My questions regarding the P70:
1) How do I update the P70 FW?
2) When I'm in the P70 menu Setup-->System-Setup-->Data Sources, any data source I select causes a reboot and the message "No Control Head". Is this expected behaviour?
3) How do I set the time/date?

Thanks!
