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.

Most non branded are OEMs, I would recommend to check online like lazada shopee for good pricing and then get local installer to install them.

Unless you get similar price in-store.

Future, if you want to use multiple application on the HU, then get 4GB RAM. 2GB works fine if you are using for basic, such as radio, phone connection, and navigation.
