A dash cover for around 8 bucks or less...

....if you're doing your headliner then it's free! Otherwise a yard of
material costs about $9 plus glue.

I attempted to fix a couple of cracks on my black 740 dash, but wasn't
satisfied. I was about to purchase either a molded plastic or carpet
cover when it hit me to make my own.

My cracks were mainly near the windshield, so I only needed a partial
cover. Having my windshield removed I did the following:

1) Made a pattern out of cardboard

2) Laid the pattern over left-over headliner material and trim to fit

3) Applied the 3M light-trim adhesive as per headliner instructions to
the cardboard and fabric

4) Install headliner fabric on cardboard

5) Clean dash with acetone

6) Apply adhesive to dash and new cap

7) Install new dash cap and set with board on top weighted to secure
front edge to hide glue.

Looks pretty good!
