Okay, I admit it, I have NO sense of direction.
Put me down at the south pole and I'd try to go south to get home.
I can relate to your "No sense of direction"
I have a very poor sense of direction and likewise for my son.
Just a couple of weeks ago, I visited Sydney and Melbourne with my family and a GPS loaned by my sister in-law sure helped like us feel like local taxi drivers.

It was particularly helpful in Sydney and it would have been impossible not to get lost there and probably wasted lots of time and even possibly gotten involved in an accident due to confusion navigating the roads.
I did not have the screen mount but my son used it to help us navigate like pros.
There were a couple of occasions when the GPS got confused because there were too many buildings that obstructed the GPS signals.
When we got into a tunnel, the GPS was unable to receive a signal, but it was smart enough to project where we were based on the speed we were traveling just before we got into the tunnel - that was quite cool.
I think if I had the windscreen mount, it would have help even more as I would be able to tie the voice instructions from the GPS with a quick glance.
My sister in law swears by it and love it.
The voice directions were fairly intelligible and if you combine it with a screen mount, you would probably be able to understand it without endangering yourself.
It does give you adequate warnings like how far you are before you reach the turn and gives you a progressive update before you make the turn.
It also allows you to tell it to avoid certain roads.
It warns you of camera junctions, that you are exceeding speed limits (if it's in the database)
But one thing it does not do is warn you of roadworks - we got stuck in a jam that had roadworks going on.
It would be ideal if it had a link somehow to local traffic conditions database.
In any case, I think a GPS is kind of free since if you have a poor sense of direction, just think of all the petrol you can save with a GPS, not to mention a lower risk of accidents that can occur from getting lost.
I never got around to using voice commands so I cannot comment on that.
