I've used this for street navigation in a few countries of Europe now.
It has found street addresses in a very accurate manner, in Belgium, the Netherlands, France, Germany, Switzerland and the UK using either full addresses or postcodes.
From a recent update (which are offered regularly) it also has a basic form of lane guidance for major autobahn type highways – what I found more interesting, and even quite useful, were the depictions of the overhead gantry signs on the German autobahns which automatically appear in the app software in good time while approaching the junctions.
Naturally, voice directions are also available.

The app had something of an apparent glitch around the area of Geneva airport; I was disappointed in this at the time and put it down to something or other to do with the density of roads in that area, or the complex international borders – later, when fiddling with the app settings I found that I had it set for a walking mode at about 4 miles per hour (which previously I did not realise existed), so I guess that this is what caused the apparent glitch. In this mode it could use all forms of footpaths as part of the routing algorithm, such as pedestrianised precincts.
It certainly hasn't misbehaved since then and it is now set in a vehicle-use mode.

This led me to look more at the settings of the app, having ignored this aspect for some time.
It's impressively detailed with various modes that can be chosen and the parameters for each mode can be preset in great detail (such as the average speed, types of roads to be used – tolled roads, ferries etc etc).
I can't find a thing this app can't do actually.
The display can also be modified and personalised to suit most things that folk may wish to view – number of satellites in use, time to destination, distance to destination, all that kind of thing.
A compass heading can also be placed at the top of the screen.

I think it also has a route tracking capability but I haven't looked into that aspect, having no specific use for suchlike.
