In this video, I show you step by step the installation process for a 6-core 64GB IPS Android screen on my 2014 LR4/Discovery 4 HSE. My car comes with 5 OEM cameras. You will use the original menus to access your cameras. When you put the car on reverse, it switches to the backup camera. This unit does not decrease your music sound quality as you can still play your music via the receiver the OEM receiver that comes with the car. There is more to discuss about this unit. I will publish a full review in Nov'21.
I hope you find this video useful!
I have no affiliation with the seller but here's where I bought my Android screen: www.aliexpress.com/item/10050...
