How to register my 1450lm


Create an account on Garmin's website and register the GPS using the serial number or plugging the GPS into the computer after downloading the Garmin communicator plugin.
The Garmin communicator plugin is an application that allows the GPS to communicate with the Garmin website.

After the GPS is registered, there will be a tab for the "Dashboard" and with the GPS connected to the computer, the dashboard will detect the serial number of the GPS and let you know if there are any software or map updates available for it.
The Garmin WebUpdater program can also be used for updating just the software (firmware) of the GPS and is a free download.

Serial number

Pull off the battery panel. In-between the 4 pin connector and the battery compartment you will find an 8 digit number.

Note the serial number is different from the unit ID which can be found by using the Garmin Mapsource software tools, or by going to:
Menu >> Setup >> System >> Menu >> Software Version

There is a serial number associated with your maps and your GPS unit. You will be able to get this serial number from Garmin when you register your software. Mapsource comes with the maps on the same disc. If it is not installed on your computer, it will automatically install.
