I have an older GS but I am having the same difficulty.
I am therefore going to make a template myself out of butcher paper (thick brown stuff). You can cut and tape it together until it suits you, then make a new (clean) template copy and show where you need folds/bends/seams etc. with a sharpie marker.
Take this to any automotive upholstery shop or one of the auto dash topper makers and they can make a custom one for you.
