I go to the Trips tab in the SkyPro app, and it says I must update my firmware. How do I do that? 

See “How do I update my firmware” below. 

How do I update the firmware in my XGPS160? 

You can do it through the SkyPro app: 

1. Plug in the XGPS160, or make sure it is at least 50% charged. 
2. Make sure the XGPS160 is on, and paired to your iPad. 
3. Open the SkyPro app, and touch the Settings icon in the upper right corner. 
4. Before proceeding, it’s very important to know that you should not exit the SkyPro app nor turn off the device during the update. 
5. Tap the Check Update button at the bottom of the Settings popup menu. This begins the update process. 
6. When the update is complete (about 4 minutes), turn off the XGPS160 and turn it back on again.
