Probably the best option to ditch them, I find the touchscreens in the Gen 3 (in fact the whole infotainment system) pretty annoying if i'm honest. I had a brief play with the set up in the Gen 4 when I did a test drive in one recently and having no touch screen option wasn't a big deal. I only wish you had the ability to switch the bloody things off completely, I find the fact you can't other than using the mute button or pausing your plugged in MP3 device, stupidly annoying.
