Another Garmin classic is when you look for how to install a micro SD card it says you can do that and then it shows you a picture of the end of an Edgge 1000, not an Edge Explore, describing how to move the rubber piece and install the card and the rubber piece is non existent on an Edge Explore. Maximize your GPS Memory. Your Garmin RV 770 LMT-S has limited storage space for waypoints, routes, and tracks. Foreign playboi carti instrumental. Videoscribe for mac. Once you reach that limit, your GPS can't hold any more data. Smart ExpertGPS users have figured out how to eke out every last bit of memory space on their Garmin GPS receivers.
Garmin Express tells me I only have 27MB free and that I need to buy a memory card. I read on the Garmin site that any 8GB card will work. I bought a 8GB SanDisk microSDHC card. When I insert the card Windows Vista sees the device and card but Garmin Express does not start as it used to and when I start Garmin Express it takes a long time to recognize the the device but does not see the card and still tells me I need purchase a card. When I try to disconnect the device in windows it tells me that it is being used and can not be disconnected even after closing Garmin Express and waiting for 15 minutes. If turn the device on with the card installed I get a white screen and nothing more. But remove the card and it starts up fine.
I can write and read to the card when it is used outside the device in my laptop. I have also formatted it to Fat32 even though it checked out fine.
After several tries now the device works with the card installed but Garmin Express does not start when I plug in the device. I have to start Garmin Express then plug in the device. And when I try to stop the device in Safety Remove Hardware it always says the device is in use and can not be stopped.
This has been and still is a very frustrating and ridiculous way to have a device work.

I'm afraid Express can be quite a trial for some. others report no problems with it. I suggest you try the older method using MapUpdater, link is here:

If I remove the SD card every thing works fine including auto launching and device shut down.
Until the use of the SD card Express work perfectly.
Hopefully Garmin will fit the problems.
It's the partitioning of the SD Card!!!
I struggled for days with my Garmin and different SD cards from all brands, qualities, speeds, specs.
Finally I found out that SD cards must be very strictly partitioned: you must have only 1 PRIMARY PARTITION on the card. Several tools on windows like Windows' disk management tool and MiniTool's Partition Editor create nested partitions.. phones and gps devices can't open those.
How I found this out is when I got home and tried to manipulate some map images. Linux saved my day and now I can navigate american maps with a european Nuvi.
So the tip here is: try to see if your SD card has been partitioned to have EXTENDED partitions or LOGICAL partitions. IF that's the case you need to delete them, create a primary partition, format it to FAT32, and re-copy your maps.
