Too simple isn't helpful at all. A paper map doesn't do much without a compass, unless you've got a topography map with easily identifiable landmarks (water, mountains, etc) & not a typical driving map. If you don't need the compass, you probably know where you are that you don't need a map either.
A cell phone is a phone, map, compass, gps, search & rescue light & flashlight all wrapped into one. None of those is perfect alone but using all available info you can get your location down to 10ft or so, fairly accurate directional headings, & go from there. Considering the cost of satellite phones/dedicated GPS units I can't think of a simpler tool to have set up ready to go. Its also always on your person to boot. FWIW I'm not talking about how to get from point A to point B, I'm talking about getting caught out in a truly desolate place. Even with pretty decent planning, s*** happens.
