Delivery Methods
Garmin maps are available in a variety of formats. They may be purchased on DVD, on a pre-programmed µSD card, or downloaded directly from the Garmin website. Many excellent non Garmin maps are also available online from multiple sources.- DVD/CD ROM: Maps purchased in this format will require a computer to use. The installation process will install the maps and BaseCamp application to your computer. BaseCamp can then be used to send maps to either your device or µSD card. Please note that most mapping products in this format are unlocked to a single device and they are non-transferable. City Navigator maps in this format can be updated by purchasing a map update, when available.
- µSD Card: Pre-programmed µSD cards are ready to use immediately out of the box. Simply unpack the card and insert into your compatible GPSr device. These maps do not need to be unlocked to your device which allows you to move the card between multiple units as desired. BaseCamp can be used to view mapping detail on your computer from compatible pre-programmed µSD cards. City Navigator maps in this format are not eligible for map updates and mapping from the µSD card cannot be copied. To obtain updated content, a new card must be purchased.
- Download: Maps purchased in this format can be downloaded directly from the Garmin website. Downloaded maps can be sent to either your GPSr unit or µSD card. All maps in this format are unlocked to a specific device and they can only be used on the device that they were unlocked to. BaseCamp can be used to view downloaded mapping detail on your computer. City Navigator maps in this format are not eligible for map updates. If you wish to obtain updated content, a new download will need to be purchased.
