This unit replaces your factory suction cup mount holder.  I created this model after my factory clip-in-mount was run over and broken.  Simply unscrew your old clip-in-mount and screw this mount to the suction cup component(can be purchased with RAM suction mount).  Stratus fits very snug.  If your using your Stratus as a backup AHARS, then you want the unit secure so that the calibration holds and does not drift.  Can be removed and replaced very quickly.  I actually used photogrammetry to capture a 3D model of the Stratus and then built my model around it.  Included are example photos of the photogrammetry process.
