Perfect fit for Kia Carnival

The designer of this van made it difficult to find a good solution for phone mount. I tried 4 different mounts until this, and it's perfect. The only problem is the holder itself- it's kinda crappy. The good news is that the mount uses standard sized ball joints so I took an old magnetic mount and mated to this, perfect phone mount.

Does not fit this vehicle. The little tabs that are supposed to click in aren't long enough. Returning.
