Thank you for contacting Garmin International.
I apologize that you're having this issue. In researching the device you have, this was a special order device and does not have an option to update maps. Because of this issue, I have started the process to refund the cost of the Lifetime maps that you purchased.
With Best Regards,
Software Support Specialist
