I just finished installing my subs to the stock system and everything works fine except my steering wheel radio controls i can no longer change tracks or adjust the volume by the steering wheel controls and have no idea why this is, if anyone has any idea why this is and how to fix it please help me. I use those controls quite a bit..

 

Sounds like you fogot to plug them back into the factory radio. If you changed the headunit to an aftermarket one, they wont work without an adapter.

 

Did you install a Aftermarket HU? if so they do make steering wheel control adaptors... I believe Crutchfield carries them but they start at around $45 and go up to i think $65...

So you have to ask yourself is it really worth it to have those controls on your steering wheel if you have a remote?
