OpenStreetMap
I recently downloaded the free Iphone app Navmii Navigator and firstly was impressed with what it had to offer for free, but secondly that there are many short comings in map detail in my part of the world.
This is also a fairly busy tourist route in the South Peninsula of Cape Town and I have good local knowledge. It is important to get it right.
I decided to try to assist with this and did a few POI amendments and additions today as a test.
Some things I don't yet understand, one is at which point are issues with a navigation system map related and when are they navigation software related?
Hopefully this will become clearer as I get involved.
The one issue I really want to fix is sections where the road seems to run in the sea on the navigator, but on the map it seems correct. How is that possible or is it a problem of old map updates?

There is a tool that checks if data is correct or not: http://keepright.ipax.at/
It will find most problems (and give you warnings when something is not clear). Sometimes the tool is wrong though (it can e.g. suggest that two roads need to be connected, while in reality, they aren't). It's up to you to decide what is right or wrong.
The flooding of the see is maybe a not-closed area. Keepright should find that. But it's also possible that it's a problem with the navigation software. (e.g. they only downloaded a part of the world, and there is a part of the area missing, which causes the see to flood the land).
As there are so many tools, I would suggest you look at the other parts of the map, and at the wiki to know if your tagging is correct. If the tagging is correct, the tool you use is wrong. You don't need to map for the tool (not for the renderer, nor for any navigation app).
For your specific question, maybe go to the help center and post your question with the coordinates and screenshots (or photo's) of that area in the app.
