    Is there an aftermarket head unit I can install in a 2006 Pontiac G6 that will still display all of the car info like MPG and Oil Life? The 6-disc changer in my wife’s G6 stopped working and it’s going to cost hundreds to get fixed. I would like to just put a nicer head unit in, but she won’t like not being able to get that information.

    Jason, unfortunately we don’t know of any manufacturer that makes an after market head unit that can still display all the factory menu options. You would have to source a replacement unit from the Pontiac dealer or local junk yard. Hope this helps. Good luck with fixing your 2006 Pontiac G6.

    Since there is no deck able to keep the info center is there a way to hook a iPod or iPhone up to the stock stereo?

    Jeff, an automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2006 Pontiac G6 aux input adapter installation.

    Are there inputs for amplifier/subwoofer on the stock 2005 Pontiac G6 6-CD changer?

  • Reply ModifiedLife May 11, 2011 at 4:26 pm

    Justin, most late model vehicles do not have RCA outputs on the factory radio to feed an audio signal to your aftermarket amplifier. You would have to install a line out converter to supply an audio output. Here is the Line-Out Converter you need:

    Scosche 2-Channel Speaker to RCA Line Out Converter

    When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. If you install a line out converter, your rear speakers will still work properly. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Pontiac G6 amplifier installation.
