My heated grips have finally arrived after having them on order for the last 5 months. My dealer kindly installed them for free so I don't know whether they came with operating instructions. For those who have not used Ducati heated grips before, they are cleverly operated by holding down the starter button once the bike has started. You can then cycle through off/low/med/high on the main display. I's nice to not have a big, ugly aftermarket switch on the handlebars.
