Titanium route type missing and another issue

I am creating a tourism app that uses the built-in map viewers for Titanium (> 3.2.0)

I seem to have 3 problems.

• on any update with the same coordinates in the same order that the route seems to change,
• the route is calculated DRIVING and there is no way to set it WALKING with documentation
• the route is typed after closing and opened once, even for that it doesn't look like an API or anything to configure
