I did and can give an update on installation once I have the time to do it.
Also FYI I actually requested they make the part available on their site by using their contact page https://www.nengun.com/enquiry/ and the option "I'm looking for a part not listed on the website"
The turnaround was pretty quick as they listed the part within a week
If you're looking for other OEM parts not available in NA you can look at the JP accessories PDF http://www2.mazda.co.jp/accessories/info_lib/pdf/cx-5_1612.pdf
Do you know where to get the installation manual for this?
