We have been having trouble seeing out of our mirrors with our new thicker strap webbing window nets. I have a Go Pro that I am going to place rear facing and split my GPS screen. To accommodate the screen being spit we are getting larger screen GPS. Getting a 12 inch but smaller probably could have worked. Splitter from Kartek. Hard wire power supply from PCI. I know people have done this before. Anyone willing to share hints on set up. Problems with dust on lens.
