Radio Replacement Interface for Select GM Vehicles with OnStar, GM-LAN Data-Bus, and With/Without Bose
• Radio Replacement Interface for Select GM Vehicles with OnStar, Bose and GM-LAN Data-Bus
• Can Be Used If The Vehicle Does Not Have OnStar
• Retains The 5.1 Digital Audio System In Select GM Vehicles
The PAC-OS4 is a plug and play interface that all for the replacement of a GM GMLAN Factory radio. It maintains the operation of OnStar in vehicles with Bose sound systems, amplified audio systems, and also audio systems without an external amplifier. The OS-4 has on-board switching that allows audio from the OnStar system to play through the two front factory speakers. This interface retains all factory warning chimes, audible turn signal indicators, factory XM Radio, and rear parking assist system. This is an all-in-one interface that eliminates the needed for multiple harnesses in specific GM LAN Vehicles.

2008 sierra
installed a pioneer 850 bt nav unit into a 2008 sierra truck
Pro, Really like the convenience wires that have the parking brake, speed wire and switched reverse power for the rear view camera!
easy to hook up but make sure you have the many plugs in real tight!
Cons, I hate the sound of the signal light I guess this is necessary? ...it's embarrassing. at least you cant hear it when the music is loud!

it works great, very easy to install. Its been in my 2011 gmc sierra for 6 months now with no problems... if i were to do it again, i wouldnt purchase this, the chime noise for it is beyond annoying and nothing like the stock sound!

found this helpful.Very Easy Install
I have a Saturn Vue 2008, and the PAC audio adapter and Steering Wheel controls worked very well to install this and my other radio. For my particular car, however, I was not able to retain factory XM radio functionality. The PAC provides 2 audio RCA plugs (L/R) for the XM, but I am unable to change the stations, so it just stays on the preview station for XM. I docked one feature point for that.
The Onstar remains functional with this, just a simple mute wire going to whatever head unit you use.
No splicing of factory wires. The turn signal chime on my Vue was occasionally not making sounds, but with this, the chime never failed. And, if you don’t want alarm chimes, you can choose not to attach the chime unit.
I’d also recommend buying the PAC Steering Wheel adapter and not mixing with Axxess since this product has the exact plug to use with a PAC adapter so you don’t have to splice additional wires. I tried with two radios, two different steering wheel adapters, and both worked well for their part.
I’m back on the market for a different radio because I wasn’t impressed with features of currently available models, but I’m definitely keeping the PAC adapter for whatever I decide to use.

PAC OS-4 SHOULD BE CONSIDERED THE STANDARD OF THE INDUSTRY.VERY NICE PIECE OF EQUIPMENT.HOOKED UP TO MY DVD
PLAYER AS STATED IN AD.HAS ALL THE EXTRA HOOKUP HARNESSES
YOU MY NEED FOR YOUR APPLICATION BECAUSE THERE ARE SOME
DIFFERENT APPS DEPENDING ON YEAR AND MAKE OF VEHICLE.
I HAVE DONE AT LEAST A FEW HUNDRED INSTALLS PROFESSIONALLY OVER A 30 YEAR PERIOD AND BACK YEARS AGO YOU DID NOT KNOW WHAT YOU MAY GET WHEN ORDERING AN INSTALL KIT.I WOULD RECOMMEND ONE OF THESE TO ANYONE DOING AN INSTALL THAT REQUIRES A SPECIAL KIT LIKE THIS.THE PRODUCT WAS AS THE COMPANY PROMISED AND YOU CAN TAKE THAT TO THE BANK. NO GROUND OR ANY NOISES THAT
CAN RUIN AN INSTALLATION WHEN COMPLETED AND TURNED ON FOR THE FIRST TIME,THANKS FOR READING,ACE.

found this helpful.Way better than schoche or metra
Had a schoche one, it started making screeching noises and some times the head unit didn't turn on or shut off when it was suppose to. Although the PAC one has a pretty annoying turn signal noise.

found this helpful.Good value
I had the PAC OS-4 installed by a professional. Everything worked as advertised, including OnStar. The only small drawback is the turn signal chime is too loud and quite annoying.

If changing head unit this is a must have, have it in my 07 Yukon Denali & I retained everything, nothing was lost, Onstar, chimes, back up sensors, turn signals, XM, etc..
