Another user has pointed out that some of you may not have already set up a UVO account on your smart phone for the first time, or may not have seen the instructions that came with your vehicle at all. As the instructions with the vehicle note, this is NECESSARY if you are trying to update the UVO firmware. If you can get into the www.myuvo.com
site, it explains all of that and what I'm going to describe below.
You can get the mobile app at either the Apple App Store or Google Play Store. Do that first if you can get into the myuvo site.
Then you need to run that app on your phone and set up an email and password and mobile number. That is the same email and password that you will then use on the UVO site.
You then set up UVO on your vehicle (follow the instructions for IN-CAR UVO SETUP) that the app specifies, turn off the vehicle, and remove the SD card. Then use the PC app to download and install the new UVO firmware (if there is any) to your SD card using your PC.
Last, you put the SD card back into your vehicle and start up the engine. Press SETUP on the head unit, and scroll down to SYSTEM INFO. Note the current firmware version number. Select UPDATE located at the bottom of the screen. DO NOT stop the engine during the update process! It takes about 40 minutes for the update to occur. Good thing gas prices are cheap now, eh?
Once the update is complete, the system will reboot either to a Disclaimer screen or the Home screen. It is normal for the screen to go black several times during this process. You can now go to SYSTEM INFO to confirm that you have a new version of the firmware. Once verified, navigate to CONNECTIVITY in the Setup menu of your head unit. Turn ON 'Enable Android Auto' or turn ON 'Enable Apple CarPlay' (depending on your phone type).
For Android phones, download the Android Auto app from the Play Store and follow instructions for that app.
To reactivate UVO, press the UVO hard key on the head unit, and select Parking Minder.
