Researched Navigator IV anti glare screen protectors
Found Vikuiti ARMR200 screen protector and 3M Natural View Screen Protector as best user reviewed for screen protection and major glare reduction. Zaggs protector had too many user complaints.
The 3M is available here in the US most anywhere (Staples, Sam's, Target etc.). The Vikuiti seems to be a European marketed product. I am going to get the 3M protector today. Cost is about $12. for the 4.3" Navigator IV screen size.
Will post follow up after I install the 3M Natural View Screen Protector on my Nav IV GPS.
