ROS navigation without amcl / localization ?

edit

Hi,

Is it possible to run ROS navigation without amcl or any kind of localization? I still want to a static map that I built using gmapping, just don't want any localization.

Would that mean I should publish a zero transform from /map to /odom? My tree earlier was map -> odom -> base_link and amcl used to publish the transform from map to odom. EDIT: I did the above but I am unable to set the initial pose of the robot in the map using rviz.

Thank you.
