Flickering displays are a sign of a failing backlight for the LCD. If device is still under warranty, contact for RMA (return merchandise authorization). If not, then the GPS is a bit dated and would be best to replace with a newer model with updated maps and Glonass satellite support. Repair not under warranty would not be cost effective
