Shaker popping issue

Hi, I'm new to this forum and need some advise/solutions.
I just replaced the Shaker1000 head unit with an aftermarket chineese nav system.
Everything seems to work fine, except the famous popping sound when I switch from one to another mode (lets say cd to radio), go into reverse or switch the radio off.
It seems to get worse when the radio is on for a while and the engine is running.
It even does it when the nav voice interupts the radio.
I did the 5v mod with a transistor (7805) so the pop is gone when switching on the unit.
I only used 1 restistor for the two wires.
The resistor works as I measured 5v output.
Could it be that I need to do both wires seperately?

Other then that I'm very pleased with the unit.

Thanks, Edwin

That was going on in my car when I bought it. The previous owner had swapped in an aftermarket head unit and every time I would start the car with the radio on it would pop and my dog would nearly jump out the window.

My solution was to buy an OEM Ford unit and toss the aftermarket in the trash.

If I were you I'd call tech support for the unit to see if they can work out a solution for you. If not then send it back.
