My advice is to install the whole solution again.
Install strech with desktop, not the lite one. With the desktop you can copy the lines from the pi webrowser and past them into the terminal. So you will do it a lot faster then tiping by hand.
Follow the tutorial in this site, until the part of “Python can”, instead of doing [pip install python-can] install manually as i told you before.
Don´t forget to activate in kodi, the part that allows internet control 8080.
One more thing, in my rns-e i did the vim hack of the firmware.
If you have a module, i think speed will never be shown in the car parameters, as the module makes the rns-e think that you are stopped.
Best regards, Rui.
