Recommendations for beginners? I have a specific project I'd like to undertake with certain goals I'd like to achieve, but I've only done some very basic programming and very little electronic/electrical work. Figuring out how to get started is a little overwhelming.

My goal is to replace my infotainment system in my car with something much more modern. There are exactly zero aftermarket replacement options for my specific car and unfortunately the stock system is tied into other systems, such as the HVAC. The stock system already has a 7" touch screen, though I'm not certain it has the same aspect ratio as the one sold on raspberrypi.com.

My dream is to pull out the factory "radio" module and the touchscreen and replace them with a raspberry pi 4 (or maybe there's a better one for this?) and the touchscreen that goes with it. I figure I'll need a DAC HAT (the car has a center speaker... maybe I want a DSP? 5.1ch?), a CAN Bus HAT (PiCAN3? PiCAN2?), some I/O HAT that I can map the physical HVAC controls to (I'm fairly certain the current system not only displays HVAC status info, but actually transmits commands from the HVAC buttons, but I might be wrong)... I'd also like a backup camera, maybe even with the moving lines (CAN Bus link the steering wheel position data?), Andriod Auto, Navigation... and if all of that doesn't max out the I/O already maybe even accelerometer/gyro data-logging and analysis and dashcam/rearcam recording.

It's ambitious, especially for a beginner... and I don't expect to have it working in the next year. I'd love to know of some resources that I can use to learn how to accomplish all of these goals. Books? YouTube channels/courses? Forums?

Any help would be greatly appreciated.
