GPS Case Positioning & Care   Some care needs to be taken to prevent the case/strap mounting becoming damaged. Be sure to position the unit correctly for viewing in use. If an adjustment needs to be made to the viewing angle be sure to release the strap tension before repositioning the case. Forcing or tugging the case around the arm with the strap tensioned is likely to result in material failure where the strap opening is joined to the case.     GPS Removal Tip   Particularly when new the mp3 case window can stick against the gps display making it difficult to remove. Keep the sale display card and place that between the two surfaces, the gps will then slide out much more freely. X Avoid excessive force that could damage the strap mount.
