I'm getting lines on my screen. It's not noticeable at a glance but it's still there. I have my NavBox underneath the rear cup holder and I have my power wires from the NavBox going to the trunk. I ran the red power wire to the positive terminal of the inverter, which is connected to my dist. block via 8 gauge wire. I have the ground of the NavBox connected to my common grounding point where all the amp grounds are on the chassis.

I've tried a 4 amp noise filter from radio shack (choke and 220uF capacitor). I've also tried a heavy duty 10 amp inline noise filter and still can't get rid of the noise. Up underneath the DVD-ROM where all the video signal cables are wired, I have the ground going to a screw on the bracket that holds the DVD-ROM unit.

Any ideas?

I had to solder extension wires from the power wires of the NavBox to my + inverter terminal and chassis grounding point. I used solid copper wire. Would this affect anything? Should I have used stranded wire instead since the power cables from the navBox are also stranded? Oh yeah, I also connected a wire from the metal chassis of the xBox to ground (from previous posts).

 

I'm not to sure with the Navbox, but I had the same problems with a DVD player. I ended up puting in noise eliminaters and it fixed it. I also had a bad power connection that was adding to the problem and when I made it a better connection it helped.

However, the main reason I am commenting is because I found a company that builds a product called a "hum bucker". It is made especially for eliminating VIDEO lines. They are mainly for video monitors and such. Anyway I talked to Frank at the company and he agreed to build me one with RCA connections instead of the usual coax conncetions. I ordered it and he said if it didn't work to send it back. Well I had fixed my problem before I got it so I sent it back. But I really thought it would be the fix. If you are interested let me know and I will find the contact info. I am guessing this could cure your problem and many others who are having it. Good luck.

 

anyone have a fix for this yet, I also have small wavy lines on my screen

 

As with any electrical noise issues, you need to determine the source of the noise. It's pretty much a trial and error method.

These links give some info about noise in a car, and might help you to understand the process of eliminating noice. The second link is a diagnostic workflow chart. While it is suited towards audio components, the procedures should be similar. You should get an idea of the trial and error process you need to go through to determine the noise source. once you determine the source, it becomes much easier to determine the solution.

 

well did you get it fix

 

Are you installing on an '05?
