Can I swap out the OEM backup camera on my 2005 LX470? I don't mind the dated quality of the navigation screen but compared to my 2016 Mazda3 the backup camera is not that great. I know there are options to install another camera with another screen or to the rear view mirror but is there a way to swap out the OEM backup camera with a new camera and have the image show up on the built in navigation screen? Really what I want is a wider FOV and maybe some guide lines. I have searched on this form and the webs but have not found anything so far. If anyone has some info I would appreciate. Thanks.
