Hi Alison,Hi everyone,
It sounds like your Uconnect system needs to be updated. You can find your current software level in your "Settings" and "System Information" tab on your Uconnect system. Please check this first. If you system is not up to date with the 18.45.01 software level the files are currently available on driveUconnect.com. If you're able to update, you will be able to download the software to a USB and update your vehicle at home. Please PM me with more information if this does not solve your navigation concerns.
The 18.45 OTA Software Update has failed numerous times (2017 JGC Summit, V-8). I am a Mac user and I have downloaded the update to my computer and directly to a USB Flash Drive, also without success. I have tried exFat and Fat32 formatting of the USB Flash Drive...neither worked. Additionally, I have done a soft reboot of the UConnect System, and a factory reset...no help. I suppose I should hoist the white flag and go to my dealership, but prior to do so, any help you provide will be greatly appreciated. Thank you in advance.
