Finding your bearings in South Korea

Hello,

While technology has definitely helped us navigate ourselves more easily in most countries, it's not the case everywhere.

How do you get to your destinations and navigate yourself in South Korea? Do you use gps systems such as google/apple maps?

Are the gps navigational systems updated enough that they provide accurate information and directions?

Is it enough to simply follow road signs in South Korea?

Is talking to locals and asking them directions the best way to get around? Are they generally friendly and helpful?

Are there any online resources or other types of resources to help you better understand the road systems, transportation, etc., in order to find your bearings?

What are the steps to take if you get lost?

Thank you for sharing your experience.
