![]() ![]() Normally choosing this would bring up a pull down menu to select a part of the map to install (due to the 550's limited memory). I had the option to choose change map coverage. SD card mounted in laptop and it only had lower 49 sw 2015.1 portion installed. I am now going to go back to the SD Card and put the Audible and MP3 folders back on the card and re-load the music I had there. I just did this and now have the 2019.10 maps for North America on my device (lower 49). Start your 550 and the maps will be downloaded or should I say, linked, to your device. I then deleted all the other folders (except the Garmin Folder) from the SD Card, ejected the SD Card from my computer and put it into my Zumo 550. The map files must remain in the \Garmin folder on the SD card. You will need to do this after Express has finished installing the map on the SD. Rename the map files (in the Garmin Folder) from gmapprom.img, gmapprom.gma and gmapprom.unl to gmapsupp.img, gmapsupp,gma and gmapsupp.unl. Now you have to do the following in the Garmin Folder on the SD Card In about two or so hours, the new maps will be updated to the SD Card. 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. As noted above, it is linked to the device. This assumes that the 550 has a Lifetime map subscription for that device. This is how I upload/add new maps to my 550. I have an active 550 that was repaired by Palmdr a few yeas or so ago. I tired to look at the Garmin website and after waiting 30 seconds it still had not loaded.
