1. Clean the unit to remove any dirt, oils or manufacturing 'release agents' that may remain on the plastic case
2. Use the guides below to determine proper placement of Velcro©
3. Cut the Velcro© as needed so as not to pass over card slots or other controls
4. Remove adhesive backing (avoid touching the adhesive as much as possible)
5. Place the Velcro© strips on the unit as far toward front as possible - press firmly to secure
6. Allow the adhesive to cure 24 hours before attaching the sun shade
   
   Because the sun shade is flexible, you can actually activate on/off switches just by pressing on the shade in the area where it passes over the switch.
