Changing out your entire navigation software stack to get a speedometer readout is like changing out you car because the rear view mirror fell off. The map data and navigation algorithms are far more important than such a tangential issue.
However if you decide not to throw the baby out with the bathwater you can actually have your cake and eat it too. ...
OsmAnd can work with online or offline (pre-downloaded) OpenStreetMap data. It offers offline search and directions (pedestrian, cycling and driving). It can provide voice guidance.
The basic application is free (no cost and no ads). There is a for-pay version which allows downloading more offline maps.
Locus Maps can do this and more. A very useful bonus feature here is it can import complete .kmz files (including images and everything) for offline use, so you can make your own travel guide (used it this way a couple of times). If you calculate your routes ahead (e.g. in the hotel, while still on WiFi), navigation should also work offline.

There is OSMand. It is a navigation app for which you can download maps, but it comes out-of-the-box with
a (low-resolution) world map,
a compass, showing
the direction to target, and

BCGSoft has a control that's called CBCGPShellBreadcrumb. Here's what it looks like.
I use many of their controls. While their documentation is somewhat poor, they provide full source code. Unfortunately, in your case, at the moment, they don't have a version of their library for Visual Studio 2013 .net languages. They're pretty good at getting releases ...

Google Maps allows you to do this by setting road types you would rather avoid or by using "alternate route" methods.
To change a driving route, click and hold a spot on the route and drag it to a new spot on the map. If you're using Maps in Lite mode, you won't be able to drag to change routes.
Basically you let it plot your route then just drag around ...

Free, but "Offers in-app purchases"
Open Street maps, or anything non-Google
I doesn't say, I need more research. At least it's not sending data direct to Google
Offline maps – preferably stored on SD card ✔ first thing that happens when you launch it is that it asks ...

it's not much of an answer but i'll find out more and inform you when ...
