Thanks Canthai,
The picture attached is from Touratech Thailand,,,no stock. Tried Touratech in Malaysia, Singapore and Vietnam..they all messaged back fairly quickly so was glad they tried and replied.
I did check all the Garmin sites also , didn't see the part listed on any of the sites here in Asia, but I may see if I can contact them directly by messenger or email..
Ive ordered a large Ram X mount, and hopefully that will work until I can get the proper Garmin mount.
