Help to build dongle (to android auto) Streaming box carpc to connect in Chevrolet Onix with Only AppleCarplay

Hi,

Due to covid 19 my Chevrolet Onix came only with Apple CarPlay and no native Android Auto

I bought CarPlay adapter but it doesn’t connect to GPS (despite built-in GPS in the box)

I have good knowledge of Android and embedded systems and rpi4 and I thought I could make this dongle myself and use a usb cable, connect the rpi4 to my car (I have a galaxy s24 cell phone) and have two essential apps on the screen (which is already built-in) of my Onix 2023: Maps and Waze (with working gps, of course)

I come to this forum to ask for the necessary steps to achieve this in the best way, from software (Operating System, etc.) to hardware, as perhaps the rpi4 is not the best option.
