I suppose it's an age thing but I do like a good map to OS standard, there's so much information.
Whilst I use a satnav, I am always frustrated because there is not enough shown to be able to confirm you are where you and it think you are.
When I started working on meter inspection, satnav's were expensive and only worked on the out code, (the first group of characters in the postcode) the company would not help with maps or satnav.
I was not a native of the areas I worked in, so it was paper maps.
Knowing what was on route, woods, open fields, high ground, water towers, rivers, lakes etc, made it all possible when trying to find a game keepers house on an estate but the estate had been divided up.
It was in awe of WW2 fighter pilots, finding their way about while flying at 200 - 400 MPH with a map!
In towns new to me, I found a base on a main road into the town. (somewhere to park).
From there I could plot a route to the street/s I wanted, I worked those, and return to plot the next batch, should I get lost (I did) I could always return to base.
Then off to the next town.
Later in the day, I would be back to the first town and call again (if needed) but in the dark!
Of course in somewhere like Cambridge or Norwich, when you arrive in the street it was usually no parking!
The company gave us cards to put in the window ("Emergency Call") but they didn't work and we had to pay our own fines.
How do/did lorry drivers manage?
