I installed this in my car for about a year, but only used it once. There were no operational issues until I removed it. Although it is in good condition, please understand that it is a used item. This is a harness that allows you to install a Toyota genuine CD DVD deck in a car that does not have the aftermarket setting. Please refer to the Beat-Sonic website for details. When shipping, I will take the product out of the box. The box will be included.
