Where I work they have trialled with a strip of velcro in the center console and it is the most stupid thing I've ever seen. Whoever thought of it needs a kick in the bollocks for stupidity.
"Oh, lets use some dodgy velcro stuff to hold a tablet onto the instrument panel ABOVE THE FUEL CUTOFF SWITCHES!!!"
Absolute genius. Of course there is absolutely no way a tablet can fall off, bounce and on the upward bounce unlock the fuel cutoff switch. Is there. Is there???
Keep it in a bag and take it out and hold on to it when you need it, or get a proper mod done. Mods are not difficult to do, it is just that most companies are too lazy to do things properly.
