Sorry, that should have been 4g ram but still hopefully enough. Pumpkin Android 10.0 Double 2 DIN Car Stereo GPS Bluetooth USB BT DAB+ Head Unit | eBay.
Not much difference in final price if you chose to buy it with the camera but I'd prefer to choose my own. Got a DBO dongle from China for $5 which should make it by Christmas for the gimmick value.
4GB is plenty enough to run Android 10 smooth enough, like I said, the 1gb I had was still fine but a bit sluggish.
Keep in mind, you can chop and splice the wiring to your hearts content if you don't get the harness adaptor, but you'll need to buy the Aerial adaptor. The Nissan one from memory is a rectangle and also sends the power to the module to amp the aerial. Pretty sure Repco and Supercheap keep the adaptor readily.
Check out AGAMA Car Launcher on Google Play, I downloaded this (paid version) and really made the head unit much easier to use and more stock.
I even changed the scheme to match my interior lights etc.
