Garmin Nuvi 3590 lmt

Back up all of it if have the room. Delete all languages, help, and keyboard files that you do not need.
In the .system directory delete All eula files.
Under Help delete all except the language you want, same under Keyboards and Text and Voice and Tutorials.
Take your time, watch what you are doing.

Do you really need extra space on your 3590? Note that your free space is bigger than the total storage of many older models and you can store lots of Custom POIs, have room for future map updates, etc., without doing anything.

But if you do want to remove files for extra space, first remember to backup your entire nuvi (having first set your computer to show file extensions, show hidden files and show system files), then look for foreign language voice, help and text files. Your biggest bang for a buck will come from removing voice files in languages you don't understand and will never use. I suggest for English speakers, that your keep American and British English, the two voices each for American and British English--and of course, the two Aussie English voices so that you can always choose Karen.

My 2460's Voice Command wakeup is "Hey Karen."

Yes he will. It was discussed in "4GB MicroSD Required For 2013.20+ Updates?" The more useless stuff on there the slower the unit will update especially as these update files grow and grow as we have seen. Depending how many poi's he wants on there, he'll eat up some more of the 2GB. I don't go nuts on poi's but I have 34MB used so far and I seem to add as time goes on.

Referring to the other thread:

http://www.poi-factory.com/node/38409

it appears to me that the consensus is that there is no need to use a SD card for map updates to a 8GB nuvi except for the rare folks who install both City Navigator NA and City Navigator Europe on their devices.

Your 34MB of Custom POIs will use about 1.7% of the 2GB of free space being mentioned. I believe that common City Navigator NA NT map updates grow at a rate of a couple/few tens of MBs with each update. 2000MB of free space will likely handle many years of updates and Custom POIs before a SD card is needed or the need arises to delete unneeded files from the nuvi's internal storage to free up space for a map update or other use.

I will agree, though, that with a computer backup of these original files if ever needed some day, I see no problem with going ahead and deleting the unneeded files that we've suggested.

Will backup the internal drive on the Nuvi 3590LMT and delete those unwanted Files..

As I said in one of my posts in there to which i'm referring to, the fuller these units get the slower they get, just like a h/d on a computer, it flies when you first get it and then it slows down as you start putting stuff on it. Get rid of the Garbage.
Unless of course you like Garbage.

That would probably speed it up too. But being an SSD, I don't think it is defragmentable. At least from what I've heard.

They are defragable. Look at the defrag.jpg
Who said they are SSD's? First off, you never defrag a SSD. Shortens life span and these things are expensive. It won't make them faster de-fragging them either. I have 2 of them. In the SSD.jpg pic, the first 2 drives are SSD's. The program can't read past 500 mb/s that's why it says infinity. The next 2 are ATA 7200 rpm 8.9ms drives. Drive N is my 3590LMT and drive P is my 3790LMT. You might want to re think the idea about these being SSD's. If that's what Garmin says, we got a problem......lol. My micro-sd card is faster than my 3790LMT. It's an 8gb card and has 1.3GB free. Kinda full.

All Nuvis will automatically defrag at boot time when required.

You can view the defrag count in the diagnostics screen.
(Some units also display last defrag date)

I thought I had seen that some where.
Good to know

Just know that if you reset some of that stuff in there you'll loose all your favorites and it puts your unit back to factory.

I thought defragmentation wasn't a big deal with flash memory (unlike most computers which have a spinning hard drive that gets fragmented). The flash solid state memory is so fast (supposedly) that it doesn't have to hunt all over the disk to find something like it does with a physical spinning hard drive. Thus, no need to defragment regularly. Another example might be an iPhone. It has a ton of memory but no way to defragment it because it's deemed unnecessary. That said, if it shows up in the developer options of the Nuvi, maybe there is a point at which it is helpful. I've found old Nuvis get slower with time even after a reset so maybe this would help. Who knows.

Sorry but I'm not clear on what your saying.
My old Nuvi 660 has a developers screen and indicates in the Defrag Count 417.

Do you mean one should do a Defrag in Windows to possibly speed it up which would do a better job then Garmins internal Defragger?

I have no intention of defragging the 660, it works superbly as is. Surpringly the battery is 5 years old and still holds an outstanding charge, I can't say the same for my 2460, the battery discharges when in storage where the 660 does not.

Where I replied that you could, and that they were not SSD's. Then WAASup posted that it does it internally. So leave it alone.

I have the 3790LMT that has the same memory as yours. I have the latest 2013.30 maps plus the AZ TOPO map plus all my custom POI's and still have 2.3 GB free. I have not deleted anything. That is way more than you will ever need for NA map updates unless you try to add all the European maps and that is the only reason that you would ever need a SD card.

When the latest map update happens the prior map is replaced so the only additional memory you would need for an update would be the difference in map size increase.

My 3590 has started to turn off as normal, but then sometimes it comes back on and then drains the battery in the 3590.

Turn off as normal? You mean sleep mode, which you can set?

Try a reboot, that may help. Make sure you backup first.

Guess what? I left my 3790 on over night by mistake, although i know it goes into sleep mode, it was still dead this morning. So there you have it. They all die if you leave it on.

This is solid state ram. How slow could it be?

Have a look for your self
C&D are my 2 SSD's. Reads infinity cause proggy can't read faster than 500 MB/S
E&F are ATA 8.5 MB/S drives
N is my 3590
O is my micro SD
P is my 3790

DARN...wrong post

But aren't you measuring the speed of the USB port and not the device?

Point well taken. Lets see if we can get this a bit more realistic. L is an external drive. It has 3 connections I used usb 2.0 for this test of course. Interesting to note the speed of the micro-sd inserted into the 3590. P=3790

Got a new 3590LMT and just love it. But how can I get rid of that stupid EULA? It's supposed to be in the .system folder, but I can't seem to find it on my Mac.

Dump all the files out of that directory called EULA
It can be found in the .system directory. Must have hidden files enabled.
