This may have been discussed elsewhere.
Can I delete all the extra voice and help files that are not in my language (American English)?
I know to make a full backup before attempting this.
Can't see how 80+% of a 7 Gig drive is taken up. The map is only a little over 1 Gig and the Junction view file is 480+ megs. What's eating up about 5 Gigs?
On my 3597LMTHD, I removed the unused language files from these folders:
I also removed the unused vehicles from the Vehicle folder.
I picked up a hundred MB or so, but after installing the 2014.40 map update, the space I gained (plus more) was gone again.
The CN NA 2014.40 map with JCV is 2.4 GB, the ASR (speech recognition) and SID data bases take up another 2 GB. The voices, vehicles, POI's. GPX and other miscellaneous files eat up another 1 GB approximately, leaving only about 1.25 GB of free space.
I have removed all these files too. Soon I will add micro SD card for storage expansion. I think this unit is smart enough to detect SD card when it runs out of disk space and will instll maps on SD card.
But it will be a while before the CN NA maps grow enough to use up the 1.25 GB of free space on my 3597, so I am in no hurry to add a SD card. The European customers will need to face the storage problem sooner, as I think CN Europe is approaching 3 GB in size. If the map file size keeps growing like it has in the recent past, the European customers may someday face the 4 GB file size limit.
Thanks for the list.
That's pretty much what I had figured. I just didn't want to have to restore anything.
Concerning the size of the U.S and European maps. I don't think the addition of roads is the problem. I think the addition of businesses and landmarks - internal POIs in the map - is increasing the map size. Seems that more and more folks are getting their business added to Google Maps and then it winds up on everyone else's map. Maybe it's the 3597, but it seem to me that there are a lot more Garmin POI icons on the screen every map upgrade.
