    Onstar module location

    Hi everyone,

    I am going to buy the Bluestar(which will allow me to use my cell phone thru the onstar system). I need to know exactly where my onstar module is located, and how to get to it. I own a 2004 cadillac deville. Any help will be greatly appreciated.

    it should be in your instructions when you get your Blue star... However it is in the trunk located on the back of the seats on the passenger side of the car.

    Hi eyekandyboats,

    Female here, and I am not mechanically inclined at all. I was looking everywhere on the internet trying to find the location of the onstar module. Hopefully the onstar module will be VERY easy to get to and connect the blue star to. Thank you so much for the help. I really appreciate it.

    Re: Onstar module location

    The module is on a large compartmented plastic panel called "electronics bay", located on the trunk side of the rear seatback frame member. To access it you remove the trunk carpeting, remove several bolts, and the entire bay flops down into the trunk. If you are not mechanically inclined, with a handful of common shop tools, find a GOOD automotive telephone/stereo/alarm installer.

    I haven't tried it, but go up in the blue bar ^^^ to the "search" tab - click and type in "onstar module" and see if any pertinent thread links show up.

    There's a bit more to this install than just a plug-and-play.

    Does anybody know where the Onstar module is located in the 2010 SRX? I bought the car and did not realize it did not have bluetooth. I appreciate your response.
