Greetings. I need some help with my 1390T. I'm trying to update with new maps, but there's not enough memory for the updated GMAPPROM.IMG file. The original is approx 1.1gb, the new one is approx 1.3gb. Are there any files that I can delete to make room?
Do you mean there will not be enough room for the 1.3gb img even AFTER the original 1.1gig file is removed? You probably have a junction View (.JCV) out there that may be quite large as well. When you do a map update you must also update the JCV file as well or Junction view will not work. That file is tied to a specific map version.
If that is the case, the best overall solution (in my opinion) would be to leave the original maps and the 1390 alone and get yourself a 4 or 8 gig microSD. That way you would have room for new maps and space for future expansion. It would also allow you room for City Navigator Maps, Junction View (JCV) and even add the City Explorer (Pedestrian option maps) to your device.
As it stands now, the 2 files taking up the space must be the gmapprom.img and the D???????.JCV junction view files. You could delete the .JCV file and probable have room for the new maps at the expense of giving up Junction views.
You "could" safely delete any language voice files you don't use, any language help files and text files you don't use. You could remove any vehicles you don't use but in the grand scheme of things, you will not recover a lot of space by doing.
With even a 2gig microSD I suspect you could put map updates IN the gps and put the Junction view file on SD.
Upgrading maps 2012 30 on nuvi 1390 if possible on the SD card
I read this forum (and others) for quite a while now trying to figure out some issues I have with upgrading my nuvi 1390T.
I own this GPS for quite a while: At first there was the nuvi guarantee (or whatever it is called), the free upgrade you get once, after buying the unit. All went well and (if I remember correctly) I got the 2010.20 or so.
I am not a big updater so I do it once a year or so.
The next time (one year after or so) I did it nicely again and everything went smooth getting unlocked maps and loading them instead of the original ones by simply copying.
Problems started lately, after a firmare upgrade. I suspect the gma protection method although my unit works without having the ...gma file righ now anywhere.
After that, I did more firmware upgrades hoping to fix another bluetooth issue. But that is another story....
Last upgrade I have done (to CNNA 2012.10) was a little more complicated: the unit would not recognise the unlocked .img files so I went the long route, installed mapsource, patched it, downloaded maps for mapsource, unlocked it with jetmouse, etc. After all the hassle it finally worked. I got the JVC file too and they all barely fitted onto the internal memory.
With the latest upgrade, 2012.30 the map was all good but the bigger jvc is huge. So I decided to create my onw selection of maps in mapsource from an unlocked version In mapsource the map shows "not lockable" which I gather is more than "unlocked" since the "unlocked" would allow me to transfer the maps but the gps would tell me "Cannot authenticate maps".
So after a lot of struggle, using different methods of unlocking and fiddling I was able to transfer as much as I wanted to the gps.
My goal is now to use the SD card for maps too, since the new map is big and I would like to benefit from the JCV (of 700MB) but I could not get the unit to recognize any map from the SD card. Remember, the maps are unlocked, I can transfer any part or the whole on the unit itself and everythig is alright, but not on the SD card.
Yes, after studying multiple threads and forums I tried /Map folded on the card, /Garmin folder , different kind of renamings on both the unit and the SD card, renaming all possible ways, gmapsupp. img, renaming the once from the unit , everything with no luck.
It seems to me that people who are still successful in loading maps and have them recognized on the SD card use an older firmware (at least)
Don't forget I am able to load the maps directly on my unit they work correctly, it is just that the 1390T only has 2GB and the big JCV file is 700MB. No go for complete CN NA. I don't need to have the whole map, right now I have a selection, small enough so I can fit the big JVC file in the internal memory. FWIW, I consider more important to have a good and picture-like view of the junction than having the map of a forgoten corner of the map.
So my question is:
Did anybody used the latest firmware (5.8) and got maps visible on the SD card? how?
Does anybody still have a old 3.6 firmware (.gcd) for the 13xx/14xx units? All the filesharing servers are down, garmin server doesn't have it anymore.
I am now trying to downgrade, update maps and then go back to 5.8 and see if that helps.
I am expecting feedback from people with a 13xx/14xx with an upgraded firmware that were able to get a map to work of the SD card. Or any other pertinent advice.
(Sorry, I don't want to offend anybody but I have tried the old ways that were working in the past for me too but not anymore)
I started this thread rather than continuing another long one of "how to upgrade" where this particular topic would fit just to keep it simple. Mods are welcome to move it in a different section.
I'm not at all familiar with Garmin GPS systems, but a friend tasked me with fixing his 1390LMT. It seems to function ok, except there is no map displayed. If I go to settings/maps/info, I get a blank page. There is no sdcard installed in this garmin. I'm suspecting that on the Garmin 1390, the maps are normally installed on the micro sdcard, and somehow, my friend lost the sdcard. Am I correct in that assumption, or should I be looking for the maps in a different location on the gps?
I did manage to get it fixed. Since this Garmin is entitled to Lifetime Map Updates, I just downloaded an updated set. It was interesting to note the despite the fact that I installed a 2gb micro sdcard, the updater did not install them on the sd card. That makes it even more of a mystery why the maps spontaneously disappeared from the internal memory. I guess that probably means that there is an intermittent problem with the gps hardware, and I can expect more spontaneous mysteries to develop in the future.
