Inaccurate Wireless Update Time Estimate

When starting a wireless map update the time estimate provided may not accurately represent the time your network can fully complete the update. This estimate, generally 2 hours and 15 minutes, is the average time it would take for a reasonably fast internet connection (6MB/s) to complete the update.

Once you start the update, your device will adjust this estimate to better match your connection speed. High-speed internet is required to successfully complete this update.
