There could be a legitimate issue behind a decision to charge for CarPlay compatibility. Car manufacturers love to charge exorbitant prices for built in nav and updates and may believe CarPlay cuts into their revenue stream (it does). Apple (and Google) do not do the engineering on the auto side programming, but instead set standards the manufacturer has to meet. This costs money too..
I guess I disagree with this. In every product evolution, there are things that start out as unique value add and over time get commoditized to just a standard feature that is expected and can't be charged for. GPS is one of those. They are welcome to charge more when they provide added value for a GPS system and the customer wants it and thus pays for it. As GPS has become a commodity freely available on your phone, people are not as inclined to pay the auto manufacturer for yet another version of what can already be had on the phone. Presently with a far better solution from Google. The auto maker may try to force customer's hand on this by not enabling AA or CP thinking customers will then pay for their built-in GPS, but some customers instead are telling them to go pound sand.
Yes, the manufacturer had an initial investment in the implementation of the AA and CP API into their audio video system, but that's where their effort ends. They are not investing anything annually, putting any effort in whatsoever after the product is sold. They built that initial investment (made a few years ago) into the purchase price of the car just like the design of any other feature. So where do they justify charging for a service annually. They are not providing any annual service. 100% of the effort is now handled by Apple and Google. All feature additions, all data in the system, all changes in the UI, etc. are all from Apple and Google. The car does not even know anything changed. No justification for the auto maker to charge except plane old greed trying to monetize something.
