Please create a folder named portrait_carlogo in the unit's internal storage, then you can download the image you like(with 420*227 pixels) into the USB drive, copy the image file, and paste it into the folder. Finally, press and hold the current car model image on the main interface to select the image to replace.
If you want to remove the home page logo, it cannot be removed, but it can be set as a transparent image with the same steps we mentioned above; we have also attached this file to this article.
