It will ask if you want to update maps (if new maps are available) and you just tell it to go ahead (well you actually have to use the mouse) Once done, you can launch Garmin Express with the SD Card still installed and it will see it as your Zumo 550. You now eject your Zumo 550 from the computer, leaving the SD Card connected. In essence cloning the Zumo's internal memory. You connect the Zumo (I took the SD Card out of mine) and the 8 gig card (freshly formatted in FAT 32) to the computer and copy all the files from the Zumo's memory to the SD Card. It requires an SD Card (I used an 8 gig card) and access to a computer with Garmin Express loaded and two USB connections so you can connect both the Zumo and the 8 gig card. Here is how to update the maps on a Zumo 550 with lifetime maps. This is the process I used the last time I updated the maps on my 550 Sure hope someone has an idea of what I may be doing wrong, or what step(s) I'm missing. gma files into the 550 and repeated the same boot-up, View Map and Favorites process with the same end result - no maps showing up on the Zumo's screen just my vehicle icon again. Loaded the SD card with the previous 2018. Erased and formatted the SD card, and then retrieved and copied my saved 2018 maps from my hard drive to the SD card.ġ0. The 550 started 'Calculating' and a few seconds later, a message popped up that said 'Unable to calculate route: no roads near starting point.'ĩ. I selected a nearby 'Favorite' from that category and pressed 'Go.'Ĩ. Selected 'View Map' and only saw my motorcycle icon - no nearby roads, streams or other geographical features. It booted up, found the satellite(s) it needed and was 'Ready to Navigate.'Ħ.

Walked outside my house and turned on the 550. Opened MapInstall, selected all the lower 49 states in the US and installed them to the SD card.Ĥ.

Opened Garmin Express, found the 2019 map file I needed and downloaded it to 'Computer Only.'ģ. gma files to my hard drive, then erased the SD card.Ģ. Removed the SD card and loaded it into my Macbook. Have a small problem that is really frustrating me at the moment.ġ.
