GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
As far as updating your garmin, as long as you h ave the keycard I can help you with that. But whether it routes to a manned or unmanned gate is going to depend on which route it believes to be the shortest, and thats not something we can change in system.
To update your maps, you need to download and install garmin express.. You can get the program from here.
Then, once the device has been connected and updated, go to this page and login to your garmin account.. Is your device now showing as one of your registered products?
