NOTE:
You must have the proper equipment needed to do a full Alignment of the radio.
Exercise a great deal of care with this mod!
Due to the placement, size, and close proximity of the surrounding traces.

If you have even the slightest doubts or the proper equipment , it would be wise to have someone else you trust perform the mod for you.

SO TAKE YOUR TIME AND DOUBLE CHECK YOUR WORK!!!!
