This solution is really not a good idea. You're essentially trying to run Apple CarPlay on Android software, and that's why you're experiencing so many issues. It's not just a matter of installing the product you purchased; you actually have to take the screen apart and add an additional board. On top of that, instead of having a genuine CarPlay system, you're stuck with a CarPlay app that runs on Android software. This means there are a lot of conversions happening behind the scenes, including audio integration, which can cause even more complications. The thing is, CarPlay was never meant to be used on Android software, so it's no wonder you're encountering all these problems. This is why it's crucial to thoroughly research and understand what you're buying before making a decision. And let's not forget about the potential consequences of modifying the screen with an added board. The factory screen was never designed for that, so you could end up having to open it up multiple times for fixes. But even if you're lucky and don't run into those issues, you're still left with the less-than-ideal situation of using Apple CarPlay on top of Android software. It's pretty mind-boggling to think about the kind of products people come up with when they lack proper knowledge of car infotainment systems.
It's incredibly frustrating and strange that when you buy something and face issues, there's no one you can turn to for help. Instead, you have to rely on searching for assistance from other people this forum. It's disappointing because you expect there to be proper support available after making a purchase. It's important to consider this aspect before buying a product.
