These directions are for updating from the basic 4" radio to a NON-Navigational Mylink radio ONLY.
1) Buy a Mylink silver box specifically from a Chevrolet Cruze. I recommend part number 23284452, but the following part numbers have also been tested: 23184129 & 23476256. (Part number 23495273 has NOT been tested, but should also work.)
Tip #1: Ask the seller to verify the radio comes from a Cruze with the same speaker setup as yours. Basic speakers is RPO code UZ9. Premium speakers with amplifier is RPO code UQA.
Tip #2: If you want/need the backup camera feature, ask the seller to verify the radio comes from a Cruze with RPO code UVC.
Tip #3: The backup camera is a standard feature on the LTZ model.
2) Buy a center console control panel from a 2013-2015 Cruze or 2016 Cruze Limited. Make certain it has an actual home screen button on it above the cd player slot. (The button looks like a house.) Also buy a 7" Mylink touchscreen and plastic display bezel. This can come from practically any 2011-2015 GM vehicle.
Tip: Shop smart and you could get all 4 parts for between $75 & $100 total, shipping included.
3) Call Anthony at MVI and order the harness kit. Contact Page
This will cost you $250. Tell them you need a Chevy Cruze Mylink Upgrade harness with Twinax cable. When asked if the radio is unlocked, tell them it is. Also tell them it is the non-navigation model.
Tip: Dhpnet has posted a diagram of their own wiring harness. Link
If you feel adventurous or are good with wiring, you can probably save money using that
instead. You will need to purchase the Twinax cable and USB cable separately.
4) Reprogram the VIN in the silverbox yourself. It's fairly simple to do and all it takes is about an hour and $15 for an usb EEPROM programmer and clip. If you don't feel comfortable taking apart the radio, ask a younger family member (preferably between 3 and 5 years old) to do it for you. You might have to bribe them to put it all back together when done however. Directions are in post #3.
4a) The recommended method of VIN change is to just zero out the vin on the new radio. That will put it into relearn mode when your vehicle is started for the first time after installation.
Tip #1: A dealer most likely will not change the VIN as this isn't an offical GM upgrade. And if they agree to do it, most likely will charge you an arm and a leg for the effort.
Tip #2: Do not send the radio to anyone advertising expensive reprogramming services. Cruze radios are moderately self contained systems with minimal interaction with the rest of the vehicle and do not need anything changed besides the VIN. (A Cruze will run quite happily without a radio installed, you however will not be very happy without one installed)
5) Installation directions are here. If you made your own harness using dhpnet's diagram, refer to that for installation.
Thanks go to modalita for their original work on this upgrade so many years ago, dhpnet for their work on a wiring harness alternative and ChevyGuy for help with figuring out the best way to change the VIN.
Mods, I know there probably won't be a lot of people interested in this thread, but can it be stickied?
