Backup camera with alpine w200

[2000F150HD]

I just installed a backup camera on my w200 and it works great except that occasionally while I am driving the monitor cuts to the backup camera for a spit second. I am guessing that it is doing this because it is very srnsitive and there is slight voltage going through the reverse wite I tapped for the signal. Anyway... I was wondering if anyone else was having this problem. Also you electrical gurus... what could I use to filter out the random voltage that is causing the HU to switch to the camera? A diode or something? Please let me know.... It is quite distracting to see the reverse cam for no reason every coulde of minutes! thanks Stephen

I'm having no problems with my install.

I had a problem with mine and had to install a relay for the power to the head unit when the camera was activated.

Here's my thread. Post #38 is where I explain what I did to fix it with a relay. If you need anymore info just ask and I'll be glad to help you.

Reverse Camera problem..HELP!!!!!

Brew...

Wasnt yours flickering when it was in reverse?

My problem is the opposite I think. My HU will flip to the camera screen momentarily when I am just driving around. I suppose a relay might fix this but i am not totally sure. I am guessing that for some reason it is sensing power when the reverse lights arent on. who knows why... I guess I could try the relay and see if it stops it.

thanks for thte input

Ok I reread your posts and I think I may be having the same problem. I think I just didnt understand what your problem was before.

Is there any way you could give me more specific instructions on the relay? Basicly just what relay to use and where to get it. It should be pretty simple to wire up... But I have never installed a relay before.

Since I'm sure I would confuse you by trting to explain it, check out the link Im posting. It is real easy to understand. Just read the relay stuff. A little further down the page it talks about adding a switch and stuff, just ignore that.

I bought my relay at Radio Shack for $6. I'ts pretty similar to the one in the picture. It will have the diagram on the side of it that shows what post is power, ground, source and switched. Look at the relay you buy, follow the link I gave you and you will be fine. Just so you know, I used a fuse tap to tap into a fuse at the fuse box in the passanger kick panel. Theres also a ground stud right on the side in the kick panel that I used. So to go by the picture in that link, #1 went to the revers light wire in the passanger door sil, #2 ground, #3 went to the fuse panel and #5 went to the "camera turn on" wire in the head unit.

I hope this helps. If you need any more info let me know. Heres the link.

And heres a link to the relay I used. Any Bosch or Hella relay of the like will be fine.
