Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I`m glad you put this up.I like a dash mat because they cut down the windscreen reflections by 90%, but it is hard to keep them in place. They come with pre-glued Velcro strips that don't stick to the dash top plastic. Kernal is on the money with the non-slip mats. You can get this stuff at kitchenware shops or even by the metre at Bunnings. I placed a piece about 200 x 100 on top of the instrument binnacle and a similar piece on top of the dash in front of the passenger, then the dash mat over the top. It works! I didn't think it would be sufficient anchorage, but my dash mat hasn't moved since. Not only that but I don't have to fight with Velcro to remove the dash mat for cleaning.
