I guess I'm old-school, but I generally use paper maps. Of course, that may have something to do with the fact that much of my job for 4 years in the Navy was open ocean navigation. Sure we had GPS, but we also used radar and even sextants. We also updated all of our own maps by hand until they were too worn, then we'd order new maps and start the updating and navigating process all over again.
Get paper maps for your area and a copy of amazon.com/American-Practical-Navi... and you'll be pretty well set. (You don't actually have to buy it through Amazon; it's just a link to show you which book is the best navigation 'bible').
And bonus in my case, I'm an expert at landnav (Army land navigation), too. armystudyguide.com/content/army_bo...
Needless to say, I don't get lost easily, and I don't need Google Maps at all.
And websites? Easy. Give the company's name, phone number, and both physical and email address, with or without a static image map, and let the user decide for themselves if they want to plug the address into their GPS or Google Maps. Most will likely opt for using email or calling on the phone. Physical addresses are often just used to check to see if the business is legit or just a scam with a registered PO Box (or your country's equivalent).
