GPS “Rollover”
 

Will the navigation systems on our XE’s be adversely affected by the GPS satellites’ reset today?

i received an email urgent warning from TomTom that my old GPS device (which I used until buying my XE) would no longer work properly unless I downloaded new firmware.

Thanks for any help!

It looks like only older (heritage) systems might be affected. Jaguar should not be an older system. I found this:

"If you own a newer commercial device with updated software, it’s most likely fine. But double check and make sure the software is up-to-date.
The U.S. Naval Observatory suggests contact the manufacturer of your GPS receiver if you have been affected by the GPS week number rollover. Some GPS receiver manufacturers can be found at the GPS World website."
