Hi All,
I joined the board to be able to add some input to this thread - I don't have a Cruze, I have a 2012 Equinox that came with the touch screen, but not MyLink - I have done months of research into the MyLink radios, because GM says the MyLink radio cannot be swapped for the non-MyLink radio. I've been looking for some answers around MyLink and iPhones, and came across this thread.
First off, for the first generation of these radios, MyLink and IntelliLink are the same thing. MyLink is the Chevy brand name for the technology, IntelliLink is the brand name for GMC/Buick. Why they decided to have two different names, I have no idea. Now, there are two generations of MyLink/IntelliLink. The first generation was released in mid-2012 in the Equinox/Terrain, Verano, followed by the 2013, Regal, Lacrosse, Cruze, Malibu, etc. It includes voice recognition for bluetooth phone calls, navigating radio stations/XM, and navigating USB connected phones, iPhones, iPods, other MP3 players, and USB sticks, Pandora, Stitcher, and bluetooth streaming audio (A2DP). GM assigns a code to all the parts in a car, this is called an RPO code. This is different than the part number, and is usually used for optioning the vehicle. The first gen MyLink/IntelliLink has an RPO Code of UFU&UP9 and the radios are built by Panasonic, and I've read that the software in them is by QNX (owned by Blackberry). The second generation MyLink is in the Chevy Sonic/Spark, 2014 Impala, and I'm not sure on the upcoming Malibu. I don't know who makes these radios, but the software is different, and has the Apple Siri integration.
The non-MyLink radio (RPO code UFU) has the same connections on the back as the MyLink Radio (UFU&UP9) - the only difference hardware wise is the addition of a bluetooth antenna on the radio. The non-MyLink radios use the bluetooth contained in the OnStar module for phone calls, and it the radio communicates with the module through the GMLAN (think of a computer network, but inside your car, where all the computer modules talk to eachother). If you have another radio, like RPO code UYE, then bluetooth comes from a module called the PDIM, which in other threads here people have swapped out to add the bluetooth functionality. There are no cables coming in or out of the screen or radio for bluetooth.
I have a feeling that your 2012 Cruze has the radio with the RPO code UYE - this would be the same radio that was in the 2011-2012 Regal. You can check the RPO code by either looking at the sticker on the radio, or, there is a sticker in your glove box that has all the RPO codes - from my experience the audio/electronics related RPO codes usually start with U. Look for UFU or UYE and let me know which one you have. I believe the LTZ trim has UFU&UP9, but the lower trims have a different RPO. Do you have a picture of the back of your radio, or did you get a good look at it? Did it only have one big black square connector, and a coax connector? On mine, the blue connection between the touch screen goes to a blue connection on the radio and is used for the touchscreen interface. The UPU and UPU&UP9 radios have about 9 connectors on the back of them.
To get around the issue with your dealer and diagrams, you can get them yourself. GM sells access to the same web-based system the mechanics use in GM dealerships - it is $20 for a 3 day subscription. The URL is www.
acdelcotds.com/acdelco/action/subscribehome You can go there and pull up the service manuals for all GM vehicles or punch in your VIN # and get it that way too. It will show you all the wiring diagrams, disassembly instructions, etc. This way you can figure out the pinouts of your connections in your car, the pinouts on the new parts (like screen, radio, etc.) see if they match, etc. I was able to determine for my Equinox at least, that the wiring system was exactly the same between the non-MyLink and MyLink radios, and all the pinouts were the same, etc.
Let me know if you have any other questions and I'll try my best to help!
