how do i change the end country if i want to leave my card in all the time while abroad.? 
When you book on and off it asks you the country you are in, just scroll up and down to change and confirm it.
You should leave the card in all the time anyway.
On the siemens, press ok, then scroll down to driver entry, press ok, scroll to begin/end country, scroll to the one you want, press ok.
ps don’t forget to do the begin country at the start of your day.

FTFY 
A Siemans remembers the last 3 different entries for begin/end country, so if you only do UK, Holland and Belgium, those 3 will be the first to come up. After that you’ll have to scroll up or down through the whole list of country letters. GB strangely is listed as UK btw.
If you’re in Spain, you’ll also have to enter the region you’re in.
As Simon says for the region is Spain or you get a fine.Ask a local for the code or it may be on the road signs.
