I wouldn't go with that.
There are many many things that can get you apart from ****e nav and technical issues. And even technical issues you have no way of knowing that you have a manufacturing defect in any of the engine components.
I would take a flight following over such terrain just so that the risk to the emergency services/wasting money while searching would be reduced. I know it wouldn't make much difference to my mortality chances but at least it would increase the chances of only me being dead. And you never know they might find you in time before all the local animals had eaten you.
And if you do manage to survive the crash...... you might survive.
