max microSD size for Garmin 62s model

The low down on file sizes

max microSD size for Garmin 62s model

https://forums.garmin.com/showthread.php?11364-max-microSD-size-for-Garmin-62s-model

Appears that the unit will only use up to 4GB.

The 62s and 62st can use up to a 32GB MicroSD card. Yes, there is a limit to ~4000 map segments, spread across all map IMG files, but you can use the extra space for large BirdsEye files and Custom Map files, amongst other things such as tracks, Geocaching GPX files, Geotagged photos, etc.

As for maps, Here is what I am able to use Simultaneously on a 16GB MicroSD Card:

* City Navigator North America - 148 segments
* Topo Canada v4 - 1224 segments
* Ibycus Topo Canada 3.2 - 947 segments
* TOPO U.S. 100K (Preloaded MicroSD version) - 431 segments

This totals about 13GB in four separate IMG files, and totals 2750 segments - leaving lots of room to add more still under the 4000 limit!

Garmin/GPX Geocaching files

Caches are loaded to the unit by placing one or more gpx files into the Garmin/GPX folder of the unit. A gpx file may contain information one or more than one cache. The total number of gpx files is limited to 200, and the permitted total number of caches represented in the 'one or more' gpx files varies with the unit model. A unit might handle 2000 or 5000 caches. Filenames can be whatever you prefer so long as they retain the *.gpx suffix.

Garmin 62s Micro SD card map problem

Bought a new Garmin 62s. So far it is a very good unit. I then ordered a pre-loaded Garmin City Navigator Micro SD card. Installed it into slot the only way it goes in and is held secure. When I turn on the GPS the message "Cannot Unlock Maps" displays and the only map available is the GPS basemap. There was no unlock code packed with the Garmin Micro SD Card City Naviagator. I did burn a backup DVD with all the data on the Garmin preloaded card if that could be the cause? Any help is greatly appreciated.

The message "Cannot Unlock Maps" tells me the card is being read. I would contact a Garmin support specialist and he will walk you through all the files that should be on the sd card. There are several files other than the gmapsupp.img that should be there. Sounds to me like you may have accidentally deleted the key unlock files.

GPSMap 62xx - comparison chart that lists how many geocaches

Does someone have a comparison chart that lists how many geocaches (as distinct from other waypoints) each Garmin model can hold?

Deleting waypoints/caches from Garmin Garmin GPSMAP 62s

Ah - OK. That question.

I swear I'm going to keep posting this same long explanation every time until the moderators create a sticky. We're now averaging more than once a week!

To the OP - in addition to the info below,
please visit http://garminoregon.....com/Geocaching
- you'll find some really good reading there that explains this and a lot more.
