>  I haven't seen an implementation for v3.


When I look at Mikes example at

http://econym.org.uk/gmap/arrows.htm

I see two problems for v3:

The first one should be easy to solve. v3 has no method

getVertexCount() and no
getVertex(i)

for the polylines. But v3 has getPath() instead that should do the
same thing in this case.

The second problem is that v3 still misses the promised "library of
spherical geometry" as an extra module. [1]

So there are no methods

latRadians()
lngRadians()

for the bearing. This is a work that has to be done for oneself.
