There are several types of touch screen, the two main ones are resistive and capacitive - I have dry skin on fingers and touch screens sometimes don't work on capacitive type. You can poke a resistive screen with just about anything, but capacitive screens ( i-phone and it looks like Honda touchscreen ) need something a bit more special, try licking your finger before touching the screen ( like a lot of people have to do before they can separate a thin plastic bag ).

I tried licking my finger at an early stage, but it didn’t seem to affect the proportion of times the screen responded to being touched.
I did find out about the two different types of touch screen, but I didn’t notice any reference to this when looking for a stylus that would work on the screen. We seem better informed than Honda. When I suggested I might be able to use a small block of a suitable material to press against the screen, and asked what properties their touch screen registers, and which materials have high levels of this property, they told me:
“
There aren’t any known problems with the sensitivity of the touch screens on our vehicles. The design of the system is to respond to a human touch and has not been designed or tested to work with any other material.
Honda (UK) do not manufacturer any particular glove or material that is designed to work with the screen so I am unable to suggest an alternative option for you.”
