I'd expect there to be a 'lot' of stuff on the subject on the web .. some of better than others.
Tristan Gooley has a few books on 'alternative navigation' ... However on a more traditional style ...

Note ... you have a substantial advantage over a walker - you have a trip meter that records how far you have come. USE IT! I zero mine when refuelling, lets me know how far I can go before I run out, and I know what direction I go from the fuel stop .. so I can plot that on the map (assuming it has the road on it .. otherwise your plotting your own course). This should give you an approximate location on the map. Most of the time this is sufficient, particularly if your map shows the road you are on.
You may then confirm + fine tune your location using any features you can see both on the map and in real life. 3 features widely separated will enable a good location - take the angle given by your compass from you to the feature ... plot a line on the map from the feature using the same angle.. 2 more lines should ideally cross at a single point ... most people will end up with a triangle .. you are somewhere around about the triangle.
You only need Lat/Long to describe where you are .. usually to other people. And there are a few Lat/Long systems .. depends on what map/s you have as to what system is used. I'd not worry about that untill you have some practice at finding your self on a map ... Go some where and try to find yourself on the map. Then travel a few miles further and try again. After the third try .. confirm your location using a GPS/phone app.
Celestial navigation ... required for ships at sea where there are no features to sight. If you need this then look at courses for sailors. You will need an accurate clock and a sextant ... easier to carry a GPS/phone!
