Guys, our car's once-great electronic systems are starting to wear out over time. Firmware updates haven’t helped, adapters keep blowing up, and the screens are getting a bit gray now too. Should I redesign the whole system from scratch, or can I extend its life with some small tweaks? As the old saying goes, "use what you’ve got at home." What’s your take on this, bro?
What should I do for outdated systems: where do I start if I don’t have hardware?

Last year, I had the same issue with my 2018 SS Camaro—adapters stopped sending signals, and the screen was a bit blurry. Everyone was saying, "use whatever you have at home," but for someone who loves electronics like me, that’s a dead end. So I took a technical approach: first, I replaced the old RS232/USB adapter with a new one, completely removing the outdated one. Then, I forcefully downgraded the firmware to an older, more stable version because newer ones tend to have more bugs. I also did an LED retrofit on the screen, meaning I upgraded the hardware, but the rest of the system still relied on the old components.
I’d suggest you try this: first, replace the renewable parts in the system—meaning the adapters—and then revert to a firmware version that works stably. If that doesn’t work, stabilize the core of the system (like the main ECU) and modernize just the visual parts (screen, camera). In my case, the system still runs on old logic, but at least it’s stable now.
Let's first check which systems are completely dead—is it the adapter or the screen that's the main issue? Well, in my opinion, you don’t necessarily need new hardware just to update the firmware; you can make do with what you’ve got. For screen issues like graying out, a simple reset or adjusting the brightness usually does the trick, and I’ve even fixed adapters by cleaning and re-soldering them. As the old saying goes, you can make do with what’s at home—you just need to figure out where the problem is.
