This sounds like someone is trying to empire build at GM to create their own version of carplay so they can be promoted.
It is even worse than that - the CEO has this pipe dream that they are going to build a Netflix sized subscription business: https://techcrunch.com/2021/10/06/gm-aims-to-build-netflix-s...
Assuming this is not a maintenance contract, who in their right mind will spend 135$ per month on "products and services" for their car?
