I'm still running my 5" GPS mentioned throughout this thread. It's been very waterproof and quite rugged. My only problem was the screen scratched easily. Mostly my own fault because I didn't put on a screen protector. It was so bad, I was considering buying another because it was getting difficult to see the screen.
Today, I polished one of my ST11 windscreens with some Novus #2 plastic polish. Worked well. I thought, why not try this on my GPS? 5 mins later, my GPS screen look nearly new... 95% of the scratches gone. I then tried the Novus #3 (courser) to get the few big scratches out. It got a few of them, so I repolished again with the #2 to get it back to nearly perfect. It's now back to nearly new looking and I'm very pleased with the results.
Thought I'd mention this for others who might have this issue, with this or any other plastic screen GPS.
