This PAC OS2-GM32 interface allows you to connect your new radio to the existing wiring in your vehicle and keep your factory features working. You'll keep the features you've become accustomed to such as safety warning chimes, the Bose amplified audio system, Retained Accessory Power (RAP), and the OnStar® system. If you have a standard Bose system, you'll be able to fade from the front to rear speakers with your new car stereo; if you have the Premium Bose system, you'll lose that ability.
The steering wheel controls for OnStar will still work, but you'll need a steering wheel control adapter (sold separately) to connect your new stereo to the Cadillac's steering wheel controls. You'll also lose the factory XM receiver.
Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this interface is compatible with your vehicle. Warranty: 1 year..
Note: Most vehicles will require additional installation parts please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

There aren't a lot of options for interfacing aftermarket radios to the Deville OnStar system. The PAC OS2-GM32 is not hard to install but finding somewhere to put it is. The cables aren't long enough to place the units units under the steering wheel and there are AC ducts and solid metal behind the radio cavity. I chose to pull out my Dremel tool and care out the bottom back plastic and place the module, chime and steering wheel interface over the ash tray which usually stays open anyway because I use it for charging my devices. I might, in the future, add some wire to the cables to allow them to be placed near the steering wheel but it's fine for now. The wiring connections are pretty much color to color but not logical in that even though it's going to the amplifier behind the back seat you do not use the preamp outputs. You are connecting the powered FL,FR,RR,and RL speaker wires to the PAC module so you would think it would burn up the GM32 or your speakers but it works. What this means is that the specs of your radio as far as 2v or 4v preamp and wattage really don't matter. When complete everything works great except for the front/rear fader. The PAC instruction sheet warns that the fader will not work when connecting to the BOSE premium system but since I had the standard radio with CD I assumed it would work but I was wrong. It's not a problem as the most common occupant of my rear seat is my dog Leigha and she hasn't complained about the volu
Pros: Works as designed
Cons: Limited placement options Chime is too loud
PAC products usually don't disappoint, but this one sure did! Had to order this from Crutchfield instead of our usual distributor because we were in a pinch and needed one asap. (We are MECP certified techs and do hundreds of car stereos a year.) This unit was very straight-forward and installs the same as any other radio replacement interface...it just doesn't work for the particular vehicle we ordered it for. 2001 Cadillac Eldorado ETC. App guide says it will work, but it does not. Will be sending this one back and ordering using the Metra GMOS-06 instead.
Cons: doesn't work, extremely big so makes for a tight fit in most GM applications, chime module is separate box instead of being built-in
Used it with installation of Nexus 7 into 2003 DeVille. Does what it's supposed to.
Cons: Chime module sounds very bad. Had a few passengers ask "What is that sound?"
Very useful. ..quick and easy to install
This is the best! Only buy from Crutchfield ! They always stand behind what they sell! And customer service rules!!!
Perfect fit and perfect performance
As with all harnesses, this was simple and straightforward. Radio does not cut out anymore as with metra.
Pros: By far superior to metra harness for my vehicle
Cons: No room behind dash, so wires need to be longer
Product makes it easy to wire up system to car....everything the car has will still function as new. Great product...just be prepared to try and find a place for all this to fit...I found room behind dash.
Pros: All wiring is included and adapts to car
Truly made the installation easy. In my wife's cadillac it worked perfectly. Thank you for the recommendation.
Pros: Easy to understand installation instructions. Works exactly as described.
Cons: could use longer leads to allow for more flexible installation options
Needed it for a 2003 deville and wanted to smash it into a million little pieces because it is so big I couldn't get it to fit the only place it could go . After hours of fighting with it I got lucky and just barely got the the unit to force into where it needed to go .
Pros: It works
Cons: Way to big for most applications
It works perfectly there's nothing else to say.
Pros: Works Fantastic
Pros: Easy hookup
Do not order this unless you are an expert at soldering wires together. I did not know this would need to be done when I ordered the product I am totally dissatisfied with this item and would not recommend it at all.
Pros: There are no Pros for this Item.
Cons: You have to cut all the wires off of your other connectors and color those wires to the wires for all the plugins that come with this unit. Then strip both colored wires solder them together then warp with black electrician tape and you have to do this for all your speakers and every other unit you have to connect to. If you are no good at soldering then you are asking for a lot of short circuits down the road and it will be pure misery trying to find them!
