Aftermarket Car Stereos, Wire Harnesses, and Adapters

Because, in order to maintain many functions, you must choose a car radio that has these functions and is compatible with the required harness or adapter. For example, if the aftermarket head unit you replace does not include this feature, you will lose it.
Retaining some other features may be more complicated, and you will often need to check back and forth: determine the features you want to retain, find a suitable adapter, and then look for an aftermarket head unit that is compatible with the adapter and the features you want.
The wiring harness is the root of all head unit upgrade, there are many ways to make it work. Some car stereo wiring harness adapters are designed to be connected to the car’s wire harness without any cutting, splicing or soldering. Other harness adapters are designed to be connected to the harness attached to your aftermarket head unit, and then can be directly connected to the vehicle wire harness connector.
