The car is a Toyota Corolla hybrid.  It is automatic, and has sat nav.  The sat nav is a bit out of date, but should work fine for most destinations.  If you are not using mobile data, I would recommend using an offline Sat Nav that just works off GPS.  I found the app Here We Go worked very well for our last couple of holidays.  You just download the map when you are online (you could do this at home), they have a map for all of Scotland.  Then just switch to offline mode in the app and it works just the same as an ordinary sat nav, just no mobile data is used.  Alternatively use Google Maps or Apple Maps with their own offline maps (they don't cover so much area)
