If the unit is properly wired up it always reverts to the rear camera when the car is placed in reverse. But if the default is set for the front camera (which I recommend) there will be a slight delay and a brief appearance of "No Camera Available" as it makes the switch to the rear camera. On the other hand if the rear camera is set for the default, the message does not appear, but you'll always have to use the remote or homelink command to switch to the front camera.
Thanks, Rich.
So just so that I am crystal clear on this, I'm going to restate this, as I now understand it:
All of the following assume correct installation (which I'm going to have done by professionals.)
--If set up with the rear camera as the default view (the mode you do not recommend) everything will function exactly as it does for me now, with no change, no delay, and I would never see that "No Camera Available" message when simply shifting into reverse. But in this mode, if I want access to the front camera, I would switch to the front camera using the remote or a programmed Homelink button to make the switch. So while parallel parking, I would have to use the remote or the Homelink button every time I wanted to change the view on the display from back to front, as the view would never change on its own simply because I was shifting between reverse and drive. Also, when I do want to simply see the front camera, I'll have to press the camera icon on the screen, but then will still need to use either the remote or the Homelink button, so utilizing the front camera becomes a two-step process instead of a one-step process.
--If the default view is set to front, when I put the car in reverse I will still get the back camera, but there will be that slight delay, and I will briefly see the "No Camera Available" indication on the screen. When parallel parking, the displays will automatically switch from the back display to the front display, as I shift from drive to reverse, each time with the slight delay and the "No Camera Available" message. When I just want to use the front camera to park, I'll only need to access the camera button on the screen, and the front camera will be immediately visible, with no delay or message. In this mode, the only reason I'd use the remote or the Homelink setting would be if I wanted to view the back camera while in drive.
Is the above a complete and accurate description?
And then one final question? Is this setup of which view I prefer as the default view a decision I need to make before installation, because the wiring is dependent upon it, or can I change the default view via the remote or some other way at any time?
Edit: I just looked at the manual which seems to make reference to buttons A and B on the remote, but in the video you talk about button D. It sounds like the button D in your video is functioning like the button A in the manual. Is that correct?
