FAQ

Frequently asked questions

Q: I installed everything correctly, but I do not see my RTI (navigation) image
anymore, what is happening?
A: As the VBB4 has 2 video entries, (1 for RV camera and 1 for any other video),
most probably the switch (Red/Black wired) is in the position it wants to show
video from Video-1. Switching over to the other position will solve this issue.
Q: Everything "works" alright, but the image of the camera is not right, it seems
like some electrical disturbance is taking place.
A: Your car has a screen which uses Negative sync for synchronising the image
nicely on the screen. Setting for this is wrong. Please OPEN the VBB4 and you will
find a "jumper" on pins 1 and 2. Please move the jumper to pins 2 and 3. That
should solve your issue.
Q: Image from camera is really fine and sharp, but image on Video-1 source is
there, but "running" on the screen and very small.
A: Most probably the source you use on Video-1 is set to PAL. The screen in your
car uses NTSC, please switch the device you have connected to NTSC output. That
should solve your issue.
Q: The VBB4 is always powered, won't that drain the battery?
A: In the end, obviously it will help drain the battery. But, in "rest" (i.e. no video
source active, screen down) the VBB4 only takes app 15mA of power. This will not
drain your battery far enough so starting is not possible anymore).
