On my TomTom 130s I used a screen protector that I cut down from one I bought on Ebay for my Ipod touch. It had three layers. It worked really well. Does anyone have a good link to a quality precut three layer screen protector for my 140s. The ones I had bought on Ebay were the same brand name that Radio Shack carried at 1/3 the cost. I don't who I bought them from now.
