I just purchased an '09 Sonata, and would like to remove the radio. Will removing the factory radio affect other functions in the car? If so, does anyone know of a module to restore any lost functions?

 

I just replaced the factory radio on my '07 Sonata GLS with a Double DIN size BOSS head unit with an installation kit and custom wiring kit I bought off of Amazon. The only function I lost was the radio control on the steering wheel but the new head unit comes with a wireless remote. Hope this helps.
