Using a 1390lmt for quite a while. At some point I had to put in an sd card because of memory. I've left it in, and things were okay until the recent map update. 2014.20 and then there was a message about having an old map.
I checked and indeed there was an old map - but where?
I ended up removing the sd card and then there were updates to apply, and the map was the old one.
So why wasn't the old map removed/updated internally?
I'm reinstalling maps now without the sd card in place, but I think the garmin isn't using the sd card properly.
Please advise what map(maps) appear in your Map Info page with the SD card inserted. Now remove the SD card and what maps are now showing.
The map version is important because Garmin's current policy for Lifetime Updates has changed. You must now download a new map WITHIN 2 YEARS, if not; you lose your Lifetime Map Update privileges.
The map on your SD card (if there) should be in the Garmin Map folder, the M is capital, and the ap is small case. It can be named anything as long as it has an .img extension.
The map if located on the Nuvi will be in the .system folder and named gmapprom.img. It should be accompanied by a gampprom.gma file and gmapprom.unl file.
If you don't see a .system folder when your Nuvi is connected to your PC you need to make the folder visible. If using Windows, in Folder Options you must:
1- CHECK “Show Hidden Files And Folders”
2- UNCHECK “Hide Extensions For Known File Types”
3- UNCHECK “Hide Protected System File Types (Recommended)”
The nuvi 1390 is a 2GB device so Garmin's options for map updates will be to either 1) install less than the full North America map update internal to the nuvi, or 2) install the full map update to a SD card.
Question: when you installed the SD card, did you 1) perform a standard Garmin map update that put the map on the SD card; 2) did you do a map update using the "clone" technique; 3) did you install some of North America to the internal nuvi storage, then use MapInstall to install the remainder to the SD card; or 4) none of the above?
The 1390 is a model that will be offered auto-install to SD (if the link is not clickable, copy & paste it to your browser):
and this is the best way in my opinion to do map updates. On my nuvi 750, when I did an auto-SD-map update, it did indeed install the new map to my SD card and also deleted the older map in the nuvi's internal storage. Your description states that the old map was not deleted and that's why I'm asking the earlier questions about how your previous map update was done.
Two last thoughts:
-You state that you're currently reinstalling the current map with the SD card uninstalled. This will definitely result in less that all of North America appearing on your nuvi with the new map.
-Are you using Garmin Express software to do map updates? If so, and given the issues you're having, I strong suggest using GarminMapUpdater rather than Garmin Express.
Please report back with your results and answers. Good luck.
