>I only need real navigation on holiday and I'm pretty sure not taking some expensive pocket computer on travel. Neither when hiking nor in a foreign country. I just print out the directions from MapQuest. K.I.S.S.

This is actually what happened historically. Various pocket devices existed for navigation (e.g. by Garmin), but they never got too popular until the smartphone became popular for entirely different reasons. Only after the smartphone become really common, then it was reused for existing applications where the benefit existed but was not that big compared to alternatives. AR/VR will need a killer application first, only then it might be reused for navigation.
