Garmin SD Card

 

I have a garmin 750 with 2009 map on it. The question I have is, can i put 2010 map on my SD card? And if so, how do i use it. Can i delete the 2009 map off my Garmin? Again, how do i do that.

I don't have SD card, but I

I don't have SD card, but I think you can have both.

See if both maps are listed in My Data. Try clicking on one. Then try to other.

I have read a lot about this on this site. You may want to search on SD Card or Multiple Maps using the Search feature for more info. I'm sure some of our experts will respond with more info soon.

wondered the same thing. i

wondered the same thing. i just updated the maps in my nuvi 850 without any problems that i've noticed.but i would have liked to have saved the original info to revert back to in case of problems. i do have sd cards in abundance!! how could i have saved the original information on a sd card before doing the new install?

size matters

If it is a normal SD card that is not locked (some of the official purchased ones from Garmin may come locked from the factory), then you should be able to erase the old maps and update to the newer ones... or if it is 2GB or larger, you should be able to load the newer maps and keep the older maps (MapSource asks you what and where you want to load). In my case my c330 has the 2008 maps built in and I have the 2010 maps (lower 48 US) on my 2GB SD card.

It shows
Capacity: 1.83GB
Used: 0.98GB
Free: 862MB

So as long as you have enough space then it should be fine.

SD storage

Just bought my 255w yesterday and am usually very good at pc and device operations. I figured out how to put data (pics,mp3,or pois on my card but as far as accessing that info on the card or finding any info at all about memory capacity on the unit itself, I just dont see it, isnt the device suppose to detect info on the card?

sd card storage

should be able to access info by going to the menu. in my case w/nuvi 850. main menu>tools>picture viewer to see pictures i've put on the sd card.

Part-a
If you have those 2010 maps as an update DVD or EXE the garming updater will do it all for you and replace/update the maps in your 750.

Part-b alternative
You could install the 2010 maps on your SD card (2gig is more than adequate) and they will show up on your map info screen along with your 2009 maps and be individually selectable on you map info screen. You now have 2 full versions. Personally I see no value to that.

Once you have both sets working you can easily replace those 2009 maps in your 750 if you like.

1. Your 2009 maps are in the the GPS garmin folder as gmapprom.img you can detete it or copy it toy your PC and then delete it. This makes room for the new maps.

2. Your 2010 maps are on your SD card garmin folder as gmapsupp.img If you simply copy that file to the garmin folder on your GPS you will have your maps replaced but your not quite done.

3. You should rename that gmapsupp.img file in your 750 to gmapprom.img. This keeps it from accidentally getting overwritten if you ever add a map your 750.

4. Lastly, if you have a file in the garmin dir of your SD card named gmapsupp.unl (you may or may not), copy it to the garmin directory of your 750 and rename it gmapprom.unl and your done. Temporarily remove your SD card and re-boot the 750 to verify that it all works.

As an fyi, if you have the 2010 maps in both the GPS and on the SD card only one instance of them will show up on your 750 map info screen. That's just how it works.

I have this setup on my c330... 2008 maps on the unit itself and 2010 maps on the SD card.
Just have to go into the Maps area of the menu and choose to use the 2010 maps and "uncheck" the 2008 maps.

Garmin SD Card

When you download the maps, you are asked for a destination to save it to. You can save it to your computer prior to saving to the Garmin.
Other question, when you plug in your Garmin to your computer, you will see a screen which askes what task you would like to perform, choose open files, or view files, click on the map file and save it to your computer before updating the new map file, same applies to music files mp3. files

This also depends on the unit... with the older StreetPilot c3xx and maybe some newer low end units, this is not an option as they are GPS only.

I transferred the 2010 maps to my SD card using the MapSource "Send To Device..."
