I have a problem on my Pioneer AVH- X8850BT can’t loading (booting), but the real cam is working. I tried to hard reset, but still doesn’t work. The display is always on position Camera View, can’t back to the main menu. Could you tell me what the problem and how to fix it ?

Hi @ntanuwidjaja ,
Is this a new installation or an existing one?
If the rear view camera is on all the time (presumably this is what you mean when you say “real” view) then perhaps there is a problem with the signal wire that tells the unit that the vehicle is in reverse gear, when it isn’t and it is turning the camera view on permanently.
Here’s a link to the user guide for the unit.
Scroll to p.56 to see the wiring connection for the reverse gear signal wire (#8). Try disconnecting the wire (wherever you can get easy access to it, also see p.51 regarding the signal wire connections) and check if the unit now will respond to other user input functions etc.
Was this answer helpful?
I have the same problem. When I boot the HU, it just goes to the camera view and I can't activate any of the buttons. I disconnect the wire to the reverse lights. I disconnected the video input too, so the picture is black. I did a factory reset. I've unplugged the HU, let it sit for 30 minutes, did a reset with a paper clip. Nothing changes the behavior. It doesn't do anything except display the camera. This problem began when I connected a rear camera for the first time. Now all my head unit wants to be is a rear camera monitor. (It is a popular name brand rear camera, not a Pioneer one).
My unit is VH-X8750BT.

I would have thought that the Home button would work with the camera display on allowing you to get into settings and turn the rear view camera to off.
Try disconnecting the lead from the reversing light that goes to the HU and check if this allows you to navigate through the HU.
It is the violet/white wire at the HU end but it may be a different colour where it connects to a reversing light
