PAC's OS-2C-CTS interface lets you replace the radio in 2003-up Cadillac CTS and SRX models while maintaining operation of the OnStar® system, warning chimes, and rear parking assist chimes. The OS-2C-CTS will work with standard GM or Bose amplified audio systems. Warranty: 1 year.
Note: This interface will not work with 2004-06 SRX models with Cadillac navigation radios. You'll lose the factory XM receiver and the ability to fade from front to rear speakers when you install an aftermarket stereo. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.
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.
Came quick, well packaged, a little confusing installation but finally got it going well. There is a lot of stuff to cram uhder the dash, very tight fit
Pros: Works well, what more can you ask
Cons: Large and good eyesight is needed writing is tiny
This keeps my onstar and door chimes working
Pros: Door chimes work. No leaving lights on or keys in car.
Cons: A little expensive but worth it.
First one I received did not work for some reason. Customer support was amazing though and had a new one shipped the day I called in and at my house with in 2 days. Put the new one with no flaw at all. Keeps everything running like stock system.
Pros: Farely easy to wire up. Just read labels.
Cons: Doesn't have full instructions on what should be done once installed.
Pros: plug and pray!! real easy hookup
Made the installation extremely easy.
Pros: Easy to install with easy to read instructions
Got it set up first try
Pros: Plugs fit my car
Cons: Could label all wires just for ease an so it's easy to learn
This item was a perfect application for installation of my aftermarket radio!
Pros: Ordering the right item was a breeze. The customer service rep gave me exactly what I needed to install my aftermarket radio.
OK, here is the down and dirty on this adapter. It's a great product, works well with my car. However, the instruction manual has TINY writing where it comes to whichg wires go where on each car - just tiny! Good thing the give the online version. Anywho, the wires from your harness plug directly into this units secondary harness, after you look up your car's wiring in the manual. It's pretty simple but a novice (like me) has to take their time on this. That said I did it per the book (and also watched it online) and it was a 1st time go - no issues.
So yes I say get it!!
Pros: Easy to connect and assemble.
Cons: VERY BULKY UNIT, and much more so when you coulpe this with several other modules like the steering wheel control module, the dinger and so on.. Not to mentione all the cables like RCA, back up cable, speakers blah blah (it's a lot of junk back there). But I made it fit!! Also, the manual has tiny very print in the appendex area - which is the most important part of this operation
It made the install in my car very easy all I had to do was put some wires together. And it still let me keep my factory amp. For the pice you get it for. It is worth it. Great product.
Piece of cake to hook up, works as it should.
Pros: Easy install
Really great radio would highly recommend. Easy to install and tech support very knowledgeable. Would purchase products in the future
At first thought it was gonna be a nightmare at first glance but just follow the instructions given and by the time u know it you will be enjoying your aftermarket radio!!!
Pros: Detailed Instructions!!!!!!!
Without this interface I didn't have the knowledge to install the unit in my cts, it just works perfectly, even the speeker wires colors are the same as the replacement stereo unit
Work perfect in a 2007 CTS
Cons: Not one
First unit i ordered didnt work. Crutchfield promptly sent . New unit that worked fine. Makes it difficult to mount head . Unit because of the size but after alot of work got it to fit..
Overview: The PAC OS-2C-CTS Radio Replacement Interface Module allows the installation of an aftermarket radio into select Cadillac CTS and SRX vehicles equipped with OnStar and a factory amplified audio system.
Note: You may use this interface even if the vehicle does not have OnStar, but does have the factory amplified audio system.
Vehicle Compatibility: The PAC OS-2C-CTS Radio Replacement Interface Module supports the following vehicles.
|SRX||2004-2006||Only vehicles without factory installed navigation radios|
Note: The OS-2C-CTS does not retain the factory XM receiver, you will lose this option when the factory radio is replaced with an aftermarket headunit. Due to the design of the factory amplified system, there is currently no way of fading from the front to rear with an aftermarket radio.
OnStar Compatible: The PAC interface module will maintain operation of the OnStar and factory amplified audio system. OnStar audio will play through the front speakers when active. Your vehicle's OnStar volume will not be adjustable (preset at medium level).
Warning Chimes: The PAC OS-2C-CTS also retains all warning chimes and vehicle rear parking assist chimes.
Steering Wheel Control Compatible (optional): The PAC OS-2C-CTS is compatible with PAC's Steering Wheel Radio Control Interface (541SWIRC, sold separately) for aftermarket radios.
