Please Note: This radio will need to be unlocked upon installation in your vehicle. It can often be put into a fully functioning test mode for 10 minutes at a time without the vehicle running but will need to be taken to a dealer for permanent pairing. The price for this varies so please make arrangements before purchase. This is for an AM FM CD Player Pontiac radio with an Aux Input upgrade that will fit many vehicles from 2000-2004. The Aux Input will allow you to use your iPhone, Android, mp3 player or satellite radio to listen to streaming music or talk radio! Simply plug your phone into the radio with a standard 3.5mm cable and it will overtake the FM radio. When you want to listen to FM again, simply unplug the cable from the radio and the unit will act as normal! The input goes directly into the radio's preamp so you won't be dealing with static or FM modulated audio! Listen to your music in clean, clear audio, the way it's supposed to sound!
