The software on many 2018-2021 GM models equipped with an Infotainment 3 System (RPOs IOR, IOS, IOT, IOU, IOV) (Fig. 1) can be updated over the air to the vehicle or via USB in the vehicle.

How do you know if the infotainment system has the latest software? Simply selecting Updates in the Settings menu on the infotainment screen does not confirm that the software is current. Unlike a mobile device such as a smartphone, the infotainment system does not look at the current version of software and go online to check for available updates.

The Update menu on the infotainment screen (Fig. 2) is only used for locating an Over-the-Air (OTA) update that has already been pushed to the vehicle, downloaded, and is waiting for user acceptance in order to be installed.

软件与校准

无线电软件更新与无线电校准不同。软件和校准不是可互换的术语。校准指示电台在软件告诉收音机如何做事时做什么。

Calibrations for the radio are not updated frequently. In the Service Programming System (SPS), the radio calibrations are updated by selecting Radio – Programming.

软件更新通常更频繁地解决修复和持续改进增强功能，例如蓝牙，设备投影（Android Auto / Apple Carplay），Sirius XM，屏幕显示和仪器集群/驱动程序信息中心（DIC）/头部的问题-UP显示（HUD）顾虑。每个软件更新都包含先前软件版本的所有增强功能，并包含数百个增强功能。

Software releases are usually announced with a Service Bulletin once the programming is available. The bulletin will list most of the enhancements included in the software update. However, due to limited text space, the bulletins are simply titled Radio Software Update.

请务必查看公告以查看软件更新中是否包含特定条件。不要假设新软件仅通过在编程更新之后看到整体无线电系统操作的变化来解决特定条件。

软件更新

Some software releases may be pushed to vehicles remotely through an OTA update. If the remote vehicle update cannot be completed, the radio must be updated through SPS via USB. Keep in mind that not all software releases are distributed as OTA updates.

如果客户拒绝了车辆更新，或者更新不成功，则需要使用新软件包重新编程无线电。

In Techline Connect, the radio software is updated by selecting USB File Transfer. Use a USB 3.0 flash drive with a minimum capacity of 16 GB when updating the software.

在继续使用USB文件传输以更新软件之前，请检查信息系统上的任何信息娱乐系统OTA更新。转到设置>系统选项卡>信息屏幕上的更新，以验证更新包是否已被远程下载到车辆。

If an update is shown on the Updates screen, the software update must be performed using the download that is present on the vehicle. Follow the prompts on the infotainment screen. (Fig. 3)

TIP:它是无线电OTA更新过程的正常运行，以便在点火器关闭时保持30秒到10分钟，并且已禁用保留附件电源（RAP），具体取决于车辆，无线电RPO和当前软件版本。一旦安装了OTA更新，无线电将返回正常的断电操作（如果已禁用RAP时）。

If there is not an update available, the Build Number must be verified before a software update is performed using the USB File Transfer.

Build Number Identification

To view the full software version file name, check the Build Number of the software. It may appear that the radio does not have the current version of software, even after a software update is completed, if checking only the software version without identifying the Build Number.

Under the About menu, select the Information icon ⓘ (circled lower-case i) on the Build Number line to see the full software version file name. (Fig. 4) In the middle of this long file name, the current software version is listed.

信息娱乐3系统具有六个不同的系列，每个系列都有一个不同的软件分支。每个分支都包含许多已释放到生产和服务的软件版本。查看字母数字名称，数字部分随着更新的软件释放而增加。

For example, after installing software version U150, Infotainment System Update v148 may be listed with a Build Number of W124E. (Fig. 5) The W124E number relates to production timing, not the software version, and is not unique to the U150 software release.

TIP:当调用TAC,软件构建数量必须be known. Telling a TAC agent the vehicle has the latest software version is like saying an engine has an illuminated Check Engine light with codes set. The exact radio software version is needed to provide the best possible assistance.

在开始之前一个USB更新

When performing a USB update, and during all programming events, the battery voltage must be stable. Preventing low battery voltage is important, but high voltage issues should also be considered. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.

A damaged or outdated battery maintainer tool, a damaged charging system, or unstable voltage from various accessories in the vehicle being on or activated prior or during a programming event can impact the programming process. Install a GM Authorized Programming Support Tool to maintain system voltage, such as the Midtronics PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642). If not available, connect a fully charged 12V jumper or booster pack disconnected from the AC voltage supply. Do not connect a battery charger.

In addition, tripping the door latch will allow easy entry/exit of the vehicle during the programming event and help prevent errors from occurring from opening a door and waking up modules while programming.

最后，删除连接到车辆中的任何USB数据端口（不充电USB端口）的所有其他设备。插入USB端口的闪存驱动器，手机或亮起充电线等项目可能会导致编程问题。检查车辆中的所有USB端口，包括隐藏在中央控制台隔间中的隐藏USB端口。

Complete All Steps

Once the remote vehicle update has completed, verify there are no additional updates. Select Settings, scroll down and select Updates. If no updates are available, verify the software Build Number is correct.

如果软件通过USB更新，请务必在工作卡（维修订单）上录制SPS保修索赔码（WCC）。（图6）在没有WCC的情况下可能会拒绝保修索赔。
