Installing Garmin preprogrammed maps/charts supplied on microSD/SD card into your Garmin sat nav or GPS device
We are occasionally asked by customers how to install the plug-and-play mapping and map updates on SD card into their Garmin device. Here we supply the answer to this question and cover some troubleshooting too.
It doesn't matter which Garmin device you have whether it's a nuvi car sat nav, zumo motorbike sat nav or Montana handheld system and which mapping you buy either i.e. Bluechart marine maps or City Navigator road maps, the answer is the same.
microSD or SD card?
In the past Garmin used to supply two versions of each map, one on microSD card and one on SD card. This was because some devices require a full size SD, while other use the much smaller microSD card. Thankfully these days this isn't an issue, as every Garmin map card ActiveGPS sells now includes an SD card adaptor with preprogrammed microSD card inside.
Locating the microSD card
A very common question we get asked is "where's the microSD?" or "the card you sent is too big". The answer's inside the SD card adaptor.
If your Garmin uses a smaller microSD card rather than a larger SD card, you will need to first remove the microSD from the large adaptor. Please see the illustration to the right which is taken from page 2 of the instruction manual - supplied with the purchase of any Garmin map on SD/microSD card from ActiveGPS.
To take the microSD card out of the SD card adaptor simply hold the SD card between two fingers and, using a thumbnail, slide out the smaller microSD card from the bottom of the larger card/adaptor.
Installing the SD/microSD card
The SD card needs to remain inserted in the slot at all times. A computer is not required. The map does not need to be activated. Simply insert the card in the slot. Preloaded mapping can occasionally override new mapping. It is sometimes necessary to open the map menu. Please refer to your Garmin user manual, but typically you would follow this procedure:
Tools > Settings > Map > Map Info
You may need to ‘untick’ any preloaded maps and ‘tick’ the newly loaded map. It may be that you only see the old maps (typically 2010.20, NT v.9 or similar). If so, please ‘untick’ whereupon the new maps should appear. These will include the identification 2016 or 2017, typically '2017.20'.
Help, the map you sent doesn’t work!
Garmin do recommend that customers continue to update their devices. This is the most likely reason why your Garmin device is not recognising the new map card. It could be that because of the increasingly larger file sizes of recent map updates you need to take a free software update from the Garmin website.
How does installing these maps affect my preloaded or lifetime map (LM) updates?
A new map on micro/SD card will not affect the maps already installed in your Garmin sat nav e.g. Garmin nuvi 2415LM (LM = with Lifetime Maps). You may need to go into your Garmin sat nav map menu and 'untick' the existing maps and 'tick' the new maps which will be on the card that you will insert into your Garmin sat nav. You will not lose your lifetime maps (to return to them, simply 'tick' the lifetime maps in the menu).
The reason you may need to tick/untick maps, especially if you buy the FULL Europe map, is that you will then have two versions of certain maps loaded at the same time. Your Garmin satnav may have difficulty deciding from where to draw the maps. Buying just the Spain/Portugal map if you only have lifetchime UK maps would not usually require that you 'untick' the UK maps.
When updating your lifetime maps online we would recommend removing the new map card to avoid overwriting the data on the micro/SD card. See the section below for further details.
Help, I cannot see the new North America map on screen
Please bear in mind that you won’t ‘see’ the North America, or any other mapping you may have purchased, until you are at that location. Trying to plan a route whilst in the UK will probably produce an error - simply because your Garmin device cannot find a driveable route across the Atlantic Ocean. The new map may need to be ‘ticked’ in your map menu (more info above). As long as see the map listed within your Garmin's on screen menu, the map will have sucessfully been installed.
Preprogrammed SD/microSD card data protection
IMPORTANT: Using preprogrammed memory cards to transfer MapSource map data overwrites the preprogrammed data. To prevent losing any preprogrammed data, use a blank memory card to transfer MapSource data. If you choose to overwrite a preprogrammed memory card, Garmin will not be able to replace or recover the lost data.
It is not possible to back up or load the maps on the SD/microSD card to the device or PC. This is for copyright and royalty reasons. If it were possible to copy these maps then multiple copies could be used in any number of devices. However, the same map SD card can be used in various compatible Garmin devices but only one at a time.
CAUTION: If uploading or downloading software please be aware that a microSD card has no copy/overwrite protection - unlike a full size SD card which provides the means for you 'lock' the card to prevent the erasing of data. To avoid any accidental deletion of card contents you need to take great care where you are transferring data to or from. If you are unsure you may wish to temporarily remove a preprogrammed map or BlueChart microSD card whilst performing software updates.
Transferring additional map information, or any other data, to a preprogrammed memory card will overwrite the preprogrammed data. Neither we nor Garmin will be able to replace or recover the lost data.
Garmin StreetPilot, nuvi 300 and 600 series sat navs
Pictured right: Garmin nuvi 600 series sat nav.
This is because these devices cannot handle the size of SD/microSD card which is in excessive of 2GB. When these sat navs were first released the full Europe map only contained Western Europe, whereas the latest map contains both Eastern and Western Europe. Similarly, the North America map used to contain United States of America and Canada, the latest version additionally now includes Mexico.
When wishing to purchase updated UK and European maps for Garmin nuvi 300/600 and the StreetPilot series, it is still possible to buy indiviual countries e.g. UK and Ireland, Spain and Portugal, the Nordics. Please click the following links to view compatible maps for these devices:
