I tried one of these mounts on my new x-25 this weekend. Didn’t have good results, the GPS signal wouldn’t stay locked on. I had it mounted on the console, so the GPS puck was sandwiched between the windshield and the unit itself. Tried my homemade GPS puck mount that holds the puck just to the side of the unit and it didn’t work either, still too many obstructions. When I took the puck off the mount and placed it in the open, it worked perfectly.
I’m going to try the new mount on my LMS320 on the bow, I expect it will work better up there (fewer obstructions).
