Help How Do I ....

Awhile back I posted about my headunit which works fine outside of the screen illuminates spuradically (sp)

When the unit is out of the car and powered by a battery or jump-pack the screen works flawlessly everytime.
However, when installed in my car, it works sometimes, other times it doesn't.

The tech from the company I purchased the unit from said it has to be grounded with a good connection to the battery. After careful thought, I'm inclined to believe this may resolve my issues.

But then my question is how would I do this? All of you electronic gurus and techies, what do you think? Could this just be a special installation need for this particular unit?? Do you think this will work??

You can try to run a ground and tap it into the negative side of the cig lighter on your dash.

ok, that seem simple enough. thanks joe

The cig lighter ground is no different than the radio ground! What the tech is telling you is to run a seperate ground to the radio. So I would run a ground from under the dash to the radio. What you do is drive a self tapping screw into the metal bracket under the dash and run a wire from there to the radio. Like I said before I highly doubt that the ground is your problem.

Oh, i didnt know that. For my under dash/door LEDs I put the ground on a screw that is on the dash frame behind the steering wheel.

You can do that also, they are telling her to basically ground the radio to its own ground source. I really dont believe thats the problem!
