Bumping this old thread because I purchased the same kit ( I assume you’re talking about this one).

Had a professional shop attempt the install and they could not get it to work, eventually telling me they believe something within the kit is defective.

Has anyone had any luck with this?

Are there alternatives to this product that accomplish the same thing?

I’ll be trying to return it, but we’ll see how that goes. The first time I ordered the kit from this company they sent me a kit for the 2019 models and never agreed to accept a return, which forced me to sell it at a loss. Ordered again many months later, I received the correct model but it’s just not working at all.
