If ownship is displayed enroute then it should be displayed on the charts provided its enabled. To enable it, pull up any approach chart, select GPS Status and turn on "Ownship on Approach". As per JeppFD, minimum required accuracy for enroute is 200m, approach is 50m and taxi is 17m. If greater, ownship is not displayed.
