This plugin is now out of date, as both Arimi and Pongo already have it in their Skins, but I don't see the need for such changes to get the coordinates and then drag them into iGO.
Once the point of interest has been found via Maps, it must be "shared" via Map2Geo (free from the Play Store) with iGO XXXX and is automatically set as a destination.

This operation only works from iGO started, strangely if you open Maps first and then share the point of our interest, iGO is started but the destination is not set ...

Send to Navigation to me doesn't work either way.
