What does it mean when a map program wants access to my contacts? 

Here.   Highly rated, wanted access to almost everything. Contacts
caught my eye.  I tapped that and instead of saying "Okay, I can live
without contacts" it said, "needs contacts". 

I didnt' copy the rest of the list but why would it possibly need my
contacts.  It's a map program and I don't put their addresses in
anyhow.   Is it going to spy on me or does it assume I'll want
directions to their place (as if I can't find it myself).  

Would you still install it, or what?

It is quite common, many map applications
provide feature of sharing current locations,
points, tracks, other data.

Why not install "App Ops Starter"?
It allows you to deny each of the specific privileges after the fact.

I'm using App Ops Starter freeware with Android 4.3 Samsung S3.
That's all I know.

It allows me to turn off access to the file system for any app on a
case-by-case basis and on a type-by-type basis.

Here, for example, is what my ChatON permissions look like:

Here's a before and after on the Automatic Call Recorder:
http://i.cubeupload.com/YTUsAt.gif

Here are my settings for that obnoxious S-Voice:

Likewise with the annoying Amazon bloatware:

I have a Nexus 5X which has such a feature built-in. It will block all
permissions by default and will show you a dialog when a certain app
wants to access Contacts, Camera, etc. A lot of apps ask a lot of
permissions although they won't actually use them.

Depends on what you call expensive.

I paid 287 euro for an LG Nexus X 16GB. ATM they are sold for 246 euro.
Same model 32GB costs 299 euro.

In 2014 I paid 348,95 euro for a (POS) Samsung Galaxy S4 Mini. Before
that I bought a Nokia N9. I don't remember how much I paid for it
exactly, but I'm pretty sure it was a lot more than 300 euro.

All the ones below are expensive by me.    If I called more people or
they called me, it might be worth it.

If calling or be called is more important, then you're probably better
off with a so-called "senior" phone:

34,99 euro

No I wouldn't be better off.   It doesn't display maps, for one thing.
And it doesn't search the web or do email for the rare but occasional
times I'll want to do that.   That I don't want to spend 250 doesn't
mean I won't spend 50 or 100. 

And I'm not a senior.  I graduated high school and college long ago.

GPS devices can be bought separately. My mother has an iPhone, but she
also uses a TomTom. It displays traffic and speed cameras.

I was under the impression your only interest was to be available and to
call...

> And I'm not a senior.  I graduated high school and college long ago. 

I didn't mean to offend. It's just a name they give. I know people my
age and younger that have a similar. They're interested in (you guessed
it) calling or being called. They want to be available. Some don't even
want to text!

First, I don't want to carry two things, have to charge two things,
fill my pocket with two things.   

Second, I thought GPSes were mostly for directions.  I want maps, not
directions.

Third, at most I'd be even, certainly not better off.

I didn't say anything about it being my "only" interest.  I said "If I
called more people or they called me, it might be worth it " to buy a
nexus instead of a smartphone that costs between 50 and 100.

GPS as subdevice/firmware of smartphones just gives numerical position.

GPS as map application uses GPS device and map/routing resources
for either giving directions
or just the position on map.

To know position is very useful for both vector and raster maps,
even if you need not directions,
or they are even not possible to have.

Like for the off-trail hiking
and/or following raster map without any routing data.

To want map application without GPS is IMHO not very wise,
especially if most current smart devices do have it.

Poutnik has helped me in the past with GPS off-trail apps and everything he
says is correct.

You do NOT need cellular data for mapping *unless* you care about traffic.
If traffic is your schtick, then you'll need cellular data.

However, if you just want routing and location and excellent maps, all you
need are two things:
a. Offline map apps
b. GPS 

Here, for example, are my Android map apps ordered from top to bottom, left
to right, in the order that I use them most:

But he was suggesting I get a non-Smart phone and a separate GPS.

I don't do off-trail hiking anymore.  I don't even do on-trail hiking
until I lose some weight or stop the pain in my back (which are
probalby related. )

It's very very rare I don't know where I am, even when traveling. What
I do need is a modern compass for my car.  I bought one at a truck
stop and gave it to my friend who died in March.  He never used it and
I wish his brother had offered it back to me, it or any other thing of
his I could have kept as a memento. 

I need to either go to a good truck stop and buy one of those, or get
a rear view mirror with a good compass.  I bought one a couple years
ago but it broke.    On my way back from Kimberton... well I never
told anyone about *going* to Kimberton.  I should make a whole post
out of it. 

Thanks for the suggestions.

Separate GPS is fine,
but with non-smart phone it may be problematic to use.

It is not necesserily about getting lost,
but about to know exactly +/- few meters where you are.

A compass usage in a car is problematic
due the car iron interference and vibrations.

Most of GPS smartphones do have HW compass,
but even then they do not derive the heading course from it,
but from GPS, what is at the car speed more reliable.

nonsense. compasses work just fine in cars and many cars come with them
built in.

actually they use both.

In a smartphone it may problematic,
but it is device and application dependent.

I am aware of that. Some of applications offer
switching from HW compass to "GPS compass" above chosen speed.

Rather, they point. How correct they are
is different, case dependent story.

Sellers sell anything the drivers are willing to buy.
