I do I do.... Touratech sell one. I bought it and then bought the Ram Mount small rail clamp and then zip tied my quad lock phone holder to the ram mount so i can lock in my iphone right in front of me. i just did a 3000km ride it was perfect. here are some pics...

 

here it is on their Aussie site so look up the USA site if you are located there for USD prices. Touratech.

 

Thanks for that but people have pointed out that this may not fit the 2016 onwards models I will have to look into this more.
