That's what thought to. The new bar adds negligible change. They only upgraded to it from the 2021 steal bars because everyone was spending money on aftermarket solutions. So why not get a piece of the pie.
Being the biggest car company in the world. Doubt they care for such a niche area. Their system now works for them and the reason they have highest revenues.
Oh that language barrier. I hated that when living there. The vagueness and indirectness added so much more time and effort to get things done. Good luck.
How is there language barrier with the dealer if you speak Japanese? Or is the language barrier English?
Anyways as others have said I'd start from the cheapest possible problem before going to the expensive part.
