Map Update/Micro SD Card

 

I went to update my maps and the message came up that I need an SD card with at least 3gb of space. The 4gb SD card in my 3597 has about 1.2gb of free space. Can I just erase the SD card, re-insert it and update? Seems to me if I am putting in a new card then I could just delete the stuff off the old card. Thoughts.

TIA

Depends

What's on the card? But in general yes.

Assuming your map update is for CN North America 2018.10 and that you have no other maps installed on your 3597, the map update can still fit in internal memory without needing a SD card. But since you are being prompted for the card, you may have some orphaned files, unused voices, archived tracks, etc. that need to be cleaned up on the 3597 before you start the update.

On the other hand, there is nothing wrong with using a SD card. If your current SD card contains map files for your current map version, you shouldn't really need to erase it before doing the update. Garmin Express will automatically delete the old map files as part of the update process.

The update will fit on the 4 GB card, but I would probably go for a larger card (8 GB or 16 GB).

Well it should but often doesn't for various reasons. Best to manually delete especially as Express is implying there isn't room by asking for a card.

Right...that's the problem...

I couldn't get it to download as there wasn't enough room and the original notice said I had to either use the SD card or choose regions which I prefer not to do.

Thanks for all you help everyone!

Cleanup.

It sure sounds like you have some junk that needs to be cleaned up ... probably some orphaned files from old map updates that need to be deleted. After you get updated to 2018.10, you can compare file names in the folders ASR, SID, JCV, and SQLite to the files listed in this post: http://www.poi-factory.com/comment/reply/46941/443143. These folders may be in internal storage as subflders of /.system and/or on the SD card as subfolders of /Garmin. You can also check the .img map files which will be in folder /.system in internal storage and/or /Garmin or /Map on the SD card.

If you suspect you have orphaned files, let me know if you would like some help in determining which files (if any) can be removed.

I got the same issue with one of my old Garmin too

I will try this weekend to see if it works. Micro SD card is cheap now a day but lazy to buy one.

Thanks!

I'll look and see what's in their...typically I don't delete files as I have pretty bad luck screwing up technology smile

"You can't get there from here"

might be best to leave it as is.

You do need to be confident in what you are doing when you start deleting things. It may be best to just leave it like it is as long as everything is working correctly.

That said, if you wanted to send me a complete directory listing of all the folders and files on your 3597 (both internal and SD) I would give you my opinion about files that I think can be safely deleted. Alternatively, I could send you a directory listing of my 3597 (where everything still fits in internal memory...no SD card needed) and you could compare it to your device.

Whatever you do (even if you decide to leave things as they are), make a fresh backup of your 3597 for safe keeping.

760 LMT Reboots loading weather map.

I think my 760LMT is missing some kind of a conf. file. When I try to bring up the weather radar its real slow to load. When it finally does load the GPS dies!! And I have to turn it back on. I was looking around in it one day and I found a log file about low memory. But that's been a year ago. I have cleaned all of the partitions with no luck. And of course it is up to date. Its not that big a deal, it only happens with the weather map but if anyone has any ideas, I'm all ears. crying

He did the exact same with me in the past, taking me step by step while answering all my questions smile

Running out of memory can

Running out of memory can cause operational problems. Get a bigger card. Minimum for any GPS is 16GB, Class 10 or faster.

Well ...

Not sure why you make that statement? Many current GPS have plenty of spare memory. Others who need SD cards only need 8Gb at most, unless you plan to load additional maps or some other data in which case a larger card may be required.

I have both a Zumo 550 and a 450. Both ran out of space for complete maps years ago. I have had to split the map between the unit and an SD card for some time now, and have with no problems. The maps work seamlessly together.

I know you'd rather not but I can tell you it's not that hard. I will normally download the Eastern portion of Lower North America to the GPS itself and then use map source to load the rest to the SD card.I choose the download to go to device and computer.

Prior to doing so I will take the SD card and put it in my computer and format it, then reinsert the blank formatted card into the GPS, start the downloads to the unit and computer.

It takes a little time and effort but the maps have surpassed the allotted internal space so it's the way to go for these older GPS's.

More memory is always

More memory is always better. Without knowing more about the OS Garmin uses, it's possible that external flash might be used for temporary storage?

Again, it's safer to just spend an extra $20 or so and buy at least a 32G SD card if that size is supported.

It isn't. And if all anyone intends to use the SD card for is to install updates to the original map 8Gb is sufficient.

You can't just make a broad statement like that.

As a rule of thumb, more memory is always better. Always. Laptop, tablet, GPS, etc.

SD storage.

I think sussamb is correct. AFAIK, all Garmin automotive devices (except those with dash cams) treat the SD card as a read only device while navigating. It is true that when connected to a computer in MTP or mass storage, Garmin software can write files to the SD card, but when navigating it is read only.

Of course, if you offload certain files like maps and JCV from internal memory to the SD card, the device will have more available workspace in internal storage.
