i just replaced my stocked HU to 9inch Android HU, by some unknown China brand, true 2GB RAM 32GB rom, Android 9. RAM checked and verified by CPU-X and MemoryInfo app.

Cost me RM365. So far the radio reception is clear, and can play netflix, astro on the go, etc.

But, just like handphone, this thing after 1-2 year need to be replaced bcos of OS and app compatibility, so imho no need to spent so much on it.
