• Diamex OBD-Hat: https://www.diamex.de/dxshop/PI-OBD-HAT-OBD2-Modul-fuer-Raspberry-PI with flat connector

The case has a slot for a DB9 plug (the side with the pins). Connect the DB9 plug to CAN_H and CAN_L of the CAN-hat; connect GND and 12V to the watchdog. Pinout is as follows:

OBD2        DB9
4,5  GND    1,2
  6  CAN_H  3
 14  CAN_L  5
 16  12V    9

This pinout should be compatible to most DB9 to OBD2 cables. One can always build one's own cable, though.

Set up gpsd, see a tutorial here: https://maker.pro/raspberry-pi/tutorial/how-to-use-a-gps-receiver-with-raspberry-pi-4. Once the "sudo cgps -s" command works, you are done.
