The above link should answer any question about adding in the radio controls for a stock radio. Perhaps a Mod can make that link a sticky? I tried to search for something on the topic as well, but could not come up with anything either.

 

we install about 3 a week sometimes, and other than chryslers sometimes loosing programming, they work perfectly. they are nice also b/c you can program the buttons on the steering wheel to do whatever you want them to do as well

 

Can you expand on this and explain what you mean by doing whatever you want? Thanks!!!

 

What street stylin' is talking about is the steering wheel control adapter for aftermarket radios. the adapter can be program to fit your needs example making the up button the mute button and down button scroll preset stations.
