Does anyone else have a squeeling sound when they accelerate with this unit? i did with my other avics too and never could figure it out. is there a 'filter" or something? this is very annoying!! please email me if you have a solution.

k, i figured out on my own what i need to get i guess. i guess i will need a Ground Loop Isolator. But hell if i know where that goes. I dont do many installs. and my install guy didnt have one. so can someone please help me? i need to get this, that squeeling, humming, noise- is killing me!! please email me at [email protected]

You can buy them at radio shack or PAC makes one that you can probably find on E-bay. They seem to make a huge difference with the Z-1, especially if your using power amps.

Ground loop isolators are a bandaid... You should actually fix the problem. What your problem is, is that your radio and the other stuff (amp, accessories etc) are not connected to the same reference ground. So essentially you' ve created a loop antennae (like a uhf antennae) Fix your grounds.. GLR's will actually give you some sound loss.
