But, yes, 20 does seem like a rather convenient number. Perhaps it has a minimum space limit, dunno.

The NA maps plus FourSquare maps take up a LOT of room. Why 20? No, not quite out of room, but there's not much left either.

Now you're asking some of the same questions I've already asked when I first started exploring the internals of this critter, and find myself still asking. I guess it's the engineering blood that flows through my body that makes me always want to 'fix' something and make it better. That is an option in the 60CSX and other units in the GPSMAP line, so I fail to understand why it isn't an option in the Nuvi line. I just want to redirect where the unit keeps it's archives. Why not provide decent documentation for those of us that ARE capable of understanding it and changing the performance and purpose of our GPS in ways that do not affect Garmin's intent or copyrights? It isn't like I'm going to find out some kind of top secret information that makes me a Double-Naught Spy. So why lock it down so tight? One would think that at least SOME of us would realize 'I shouldn't have done that!' and can go buy another unit if we brick one.

There are enough warnings and documents about those warnings as well as an end user license agreement and a dozen other bits and bobs to guarantee that Garmin is not responsible for me bricking my GPS. Garmin protected the nuts and bolts of the GPS OS a little too tightly.

Configuring the device as an MTP device makes very little difference in Windows 10, either, except that it's harder to refer to it in scripting. Scripts fixed, but still, that's all tangential. IIRC, the original drive ID's were E, F, and G, because the reassignment hosed up a few scripts I had hard-coded addresses in. That's strictly a Windows thing, and I've actually had them change a few times when I add a new device. Other tidbits disappeared in the firmware 'upgrade', too, some of which were cute, some not so much or of much value.

But Garmin didn't ask my opinion (nor that of any other semi-advanced user). That's one of the things that actually delayed my 'upgrade' to the 2589 LMT that I now have.

That was a new thing starting in about 2012, and frankly, I can't really understand WHY there was a need to change the method of saving and archiving the tracks. The 255W did not record tracks in the Current.gpx file. With a little diddling, I even got it to report current county with 3rd party maps. Current.gpx had very little info in it other than current position, elevation, time, and heading. The 255W that I had would create a new tracksxxx.GPX file as it filled up the one it had open (roughly 10000 points). I'm quite familiar with the structure of the Nuvi, old and new, because I've had one of some flavor since 2008. I've captured some of them, some I haven't.

Pretty much exactly what I was describing, however, I have 20 of the GPX files in the Archive, numbered 142-161, meaning the at least some of the first 141 have all gone to binary heaven, and a great deal of tracks (within each archive file) gone. Unfortunately, the sun gods got that one. It's not nearly as flexible as was the 255W that I had before. I was pretty disappointed in this Nuvi firmware version. Guess I'll keep scratching to see what I can do beyond getting a small laptop to put all my GPS activities on. The caching app in it leaves a little to be desired as far as different cache types are concerned (only one type can be selected as geocaches), but it's a lot better than nothing. If the SD card is removed, the 60CSx will automatically revert to writing to internal memory. The 60CSx can either transfer the tracks to the SD card, OR, it can be configured to keep the tracks straight on the external memory. Even if I could manually save the tracks to the SD card (without connecting to an external smarter device), as I can with the 60CSx I would be much happier.

I'm almost positive that this thing did have an option to record to the SD at one time.

Not that they'd even consider it, but perhaps a software update from Garmin could help. This is why I was hoping there was a way to redirect the track files to the SD Card. I'm sometimes on the road for many days, away from my home PC. Each time I power it off, it creates a new log file, meaning at least twice a day, so I get to keep about 10 days worth of tracks, assuming I don't turn it off every time I get in and out of the truck. Unfortunately, that isn't always convenient.
