I logged onto "My Garmin" and was told I had a software update available. Downloaded it. Then downloaded the Map Update (from 2012.10 to 2012.20). After the download finished and unit was ready to install, a message came up that there was not enough room in the unit for US and Canada maps (which i DID have previously), so I had to settle for the US only. WHY????? I have an external 2GB chip in the unit, so what can be done? I sent an e-mail to Garmin Tech Support which they acknowledge receiving, but no response yet. Anyone else run into this?
Your nuvi 1450 has 2GB of memory so this is not unexpected:
My nuvi 750 has just 2GB of memory and by removing unneeded voice files, etc., I was able to install all of North America to it for 2012.20--my fingers are crossed that I'll be able to say the same after the 2012.30 update soon. (Note to you and myself--when buying our next Garmin GPS, check the link above and buy an 8GB--or at least a 4GB--model to best be able to handle future map updates.)
Assuming you have lifetime maps, don't sweat the current problem as a new map (2012.30) is due out most likely in the next week or so.
Before updating to this map, do a full backup of your current nuvi contents to a computer to be safe, then delete all unnecessary files from the nuvi including voices, help and text files in languages that you will never use, unused vehicles, etc. There's no need to keep Danish, Finnish, Afrikaans, etc., especially if you don't speak these languages.
If all of North America in the 2012.30 map still won't fit after these deletions, folks here will walk you through the procedure to install the remaining map areas to your SD card.
To be able to install map portions to your nuvi's SD card, be sure when doing map updates to install the update to your GPS and your computer. Note that the default installation is to the GPS only, so when doing your next map update, click the "Install Options" button when it appears and choose "Install to GPS and computer."
Once again, thanks to bear007 for starting the process of determining the memory in the various Garmin devices since this is something Garmin does not make easily available to owners and potential buyers.
Yet those that manually place the maps on their 1490s (LMT versions so they have "free" updates), have absolutely no problem installing Canada, US & Mexico.
Makes you wonder if the "hackers" should be working on Garmin's "install" software.
On my Nuvi 1450, I deleted unnecessary Voice, Help and Text files and finally got Map Update 2012.20 installed, but the unit now has only 162 MB of free space, not enough, I fear, for 2012.30 etc. etc.
Will someone please give me the necessary steps to download to the 2 GB card that is already plugged into the unit? At this point, it is empty with 1.83 GB available.
How big is the .jcv Junction View file on the 1450? It might be better to move the jcv file to a SD card which would free up oodles of space on the nuvi thereby allowing future full maps to be directly installed to the nuvi, with JV images coming from the SD card, thereby avoiding a split map installation.
With 162MB of free space now, you're doing well by thinking in advance before doing a map update.
A question for anyone: have we found that all JV-enabled devices can use the .jcv file from a SD card? If not, what model or series can't run JVs from SD?
Which folder do you find the JV file in or what is the name of the file? Just looked through the folders and didn't find a file for JV.
It appears to be in the .system/jcv directory in your series of nuvis from this thread which indicates that jcv files on SD cards do work in your nuvi model line:
To see the .system directory in a Windows PC, you probably need to tell your PC to display System and Hidden Files (See your PC's Control Panel/Folder Options):
· Click Start > Control Panel > Folder Options
· On the View tab, choose Show hidden files, folders, and drives
· uncheck Hide protected operating system files (Recommended)
· Click Apply to save your changes. Click OK to close the window.
Your jcv file will be the only large file in the jcv directory and will be named something like D......A.JCV. There may also be a tiny .sum file which is a checksum and can be deleted...you will do a backup before attempting anything, right?
