2006 Naviagtion System Screen Protectors

I've purchased several screen protectors for my digital camera and PDA from a company called Invisible Shield. Unfortunately, they don't make a screen protector for the Honda Navigation System, but they do offer a custom made solution. http://www.shieldzone.com/category/custom_orders/

My problem is that I haven't take delivery of my new Accord yet so I don't know what the Navigation System screen size is. Could somebody measure their screen size and post it here?

Thanks,
Kelly
