how do i transfer maps from mac to gps?

[cookie]

in the past when i've updated, i have checked the option to install updates on my mac and the gps. i did that this time and after finally downloading the latest update i got a message that there wasn't enough room on the unit. options to make room were greyed out, so i switched preferences to install only to the mac.

thought i'd use the map install tool, but that 54.9MB free (40.2MB used), which apart from making no sense to me (i thought there was 4GB of storage) doesn't leave much room for any more maps.

how do i get to overwrite the existing maps?

is this an unusual problem then?

surprised that there's no replies

The MapInstall program creates a supplementary mapping file (named GMAPSUPP.IMG), this is overwritten each time you use MapInstall to write to the GPS. The Full European mapping in installed as a file called GMAPPROM.IMG. As such this is relatively protected from being overwritten. This is still there on your Zumo, hogging virtually all of the space.

Simple solution is to put a card of at least 4GB into a card reader and user MapInstall to write a GMAPSUPP.IMG file of the mapping you need. This can then be put into your Zumo and of you go (you may need to check the 2012.40 mapping within the menus on the GPS and uncheck the previous version).

If there's a GMAPSUPP.IMG file on the GPS (in the Garmin folder) then move this to your PC or delete it.

The mapping on your Mac needs to be fully unlocked, not sure if this is done by default on a Mac as part of the mapping update, usually is on a PC.

You can rename the GMAPSUPP.IMG file to GMAPPROM.IMG and replace your existing one in the Garmin folder on the unit. You didn't say if you have a Zumo 550 or 660 though by the mention of 4GB I assume the latter. As info for others who read this; the 550 will only fit part of Europe for the 2012.40 update and the 660 will need some tweaking (removal of unused voices in the Garmin/Voices folder is usually enough along with deleting any GMAPSUPP.IMG file on the device) to fit it all on.

Good luck.

any idea why this doesn't get overwritten by the install process? isn't that what's meant to happen?

i have a card in the unit i could write to with Map Install. at least it seems like i can write to it.
i have this nagging anal-ness that make me want it on the unit memory though.
i suppose i really want to make it work as intended and avoid all this mucking about next time.

i will try your suggestion of moving the file.

the mapping on the mac appears to be fully unlocked. i can zoom right in and get detail.

it's a 660.

thanks for the help.

Not sure but the cynic in me says - lots of the base Europe map will not change ie. rivers, international borders, major roads, tunnels like the Simplon,Mont Blanc etc. So to keep it easy they are all on a "Master Map" - GMAPPROM.IMG. Now all the other stuff that will change quickly is the POI stuff.The paid for advertising, by that I mean I would imagine McDonalds/Burger King et al pay to have their burger bars stores etc placed on the database so we can find Hotels, Petrol Stations etc and this is most of what is in the GMAPSUPP.IMG file. This sort of stuff could change relatively quickly and need updating to keep the subscribers happy hence a "Supplementary file".
As I say a cynical guess maybe but I think I am maybe not too far off the mark.

Yep I agree, I got a touch of the old OCD too!

The update overwrites the GMAPSUPP.IMG file but only if you run the web updater to write to your GPS. The GMAPSUPP.IMG file is intended for supplementary mapping in addition to your std. City Nav Europe (or whatever region is home). This supplementary mapping might be City Nav for another part of the World your're visiting, say the US. Or it could be topographical maps etc. That's how it was designed back in the day when they developed the first NT PNDs (StreetPilot 2720 and Quest II). The older StreetPilot and earlier just used one mapping file, life was simpler in those days...

i have a card in the unit i could write to with Map Install. at least it seems like i can write to it.

You can do it this way, ensure that you have enough room on your card for the mapping you want to load. It will write the GMAPSUPP.IMG file to a folder called Garmin. If running a Zumo 550 ensure that you have the latest firmware otherwise it can't deal with IMG files bigger than 2GB. Writing to the card in a card reader will be quicker that if you have the card in the unit, especially the case with the 550.

i have this nagging anal-ness that make me want it on the unit memory though.

You can do it this way as well. Write the mapping you want to a spare SD card, CF card or even a USB memory stick. This will create the GMAPSUPP.IMG file as above, in a folder called Garmin. Simply rename this to GMAPPROM.IMG and move it to the Garmin folder on your GPS. Best to maybe copy the existing GMAPSUPP.IMG file to your computer as a backup until you're sure everything is OK.

City Navigator Europe now won't fit onto the Zumo660 if you don't make a little extra room.

Remove any surplus voice files from the Garmin/Voices folder, you should only need the UK_English ones. Web Updater will offer to reinstall these next time around, make sure you only update the ones you have left on. If there's a GMAPSUPP.IMG file on the unit memory move that to the Garmin folder on the SD card (if there isn't such a folder create one) or delete it.

The above should allow you to just squeeze on 2012.40 the official way using Web Updater.

Next time around you'll need to build a custom map-set using MapInstall.

When building the mapping on your computer rather than running the official update the Junction View (those images of upcoming junctions you get on the 660) will no longer work, according to Garmin it's version specific. In the States they release this file separately for each mapping update, I've asked Garmin UK but quite frankly they're useless when it comes to this sort of thing. There may well be one for Europe 2012.40 out there on the net, haven't looked for it in earnest yet. The upshot of this is that you can delete the xxxxxxxx.JCV file in the JCV. xxxxxxxx will be a number sequence. This file is pretty big and will claim back a lot of space. You don't need to do this this time around.

I'm not sure if the 3D buildings file is version specific but, by default, that lives in the Garmin folder on the unit. This can be moved to the Garmin folder on the SD card. I would recommend that you do this for 2012.40, it'll give you more space on the internal memory for routes, tracklogs etc.

All the above should clear enough room on a 660 to fit all of City Nav Europe on for quite a few years to come albeit without Junction View.

i suppose i really want to make it work as intended and avoid all this mucking about next time.

Given the current size of City Nav Europe and the fact that it grows quite a bit with each iteration you'll be having to build the mapping and manually installing from now on.

i will try your suggestion of moving the file.

Try having a clear out and doing the official on-line (tedious) install, as above, first. That way you'll retain Junction View.

Sorry, rushed my earlier post as was due in a meeting...

the mapping on the mac appears to be fully unlocked. i can zoom right in and get detail.

There are two levels of unlock. One allows use on your computer, the other is GPS device specific. On the PC mapping doen via the on-line update is fully unlocked, that's why you have to plug in your Garmin.

very good explanations

i've not had time to go back and try any of your suggestions yet, but i hope to get to it soon.

looks like i'll have to download the files again if i want to keep the junction view feature.

garmin really can't do software at all

thanks for the help

You'll need to ensure that you have enough room to fit all of City Nav Europe on.

The following are the relevant file sizes for 2012.40 as reported by Win XP, you mileage may vary slightly:

GMAPPROM.IMG - 2,509,312 KB
GMAP3D.IMG - 455,600 KB
xxxxxxx.JCV - 626,318 KB

Having had a clear out of voice files and any GMAPSUPP.IMG (if there is one) take the sizes of your existing files as above and add that to the free space reported to give the clear space without existing mapping. If there's enough room to fit all the above (3,591,230 KB) and some room to spare then you should be OK for the update.

After the update you might want to move the GMAP3D.IMG file, and any files starting GMAP3D, to the Garmin folder on the SD card. This should give you some elbow room.

ok, i cleared out the GMAPPROM.IMG from the gps + some non-english voices (but they were only 4kbs each).
i tried to use the lifetime updater to install to the gps, but it insists i have the latest maps, so won't go any further.
i then thought i'd try using map installer, which seemed to go ok, but i have a couple of questions.

i now have this in my map list:

no idea where the 2010.10 mapping is or why it's listed. also why is the 3D map still .30 and do i need it? what does it do?

If you've used MapInstall rather than the web updater then you still have a GMAPPROM.IMG file on your system with the earlier mapping. MapInstall will create a GMAPSUPP.IMG file.

Plug in your Zumo and look in the Garmin folder in the internal memory.

The 3D mapping is for the 3D building eye-candy, if you don't use it delete the file GMAP3D.IMG or move it to your PC if you're the cautious type.

Your GPS needs a good clear out TBH, you have three generations of mapping, of various types. in there.

i deleted the GMAPPROM.IMG file from the gps. before i did that, MapInstall would not update the maps on the unit.
i'm almost certain that there was no GMAPSUPP.IMG prior to update. the only GMAPPROM.IMG file on my system was the one on my desktop after i'd moved it from the 660

this is how my Garmin folder on the 660 looks now

i should delete the 2 files highlighted then, or is the GMAPSUPP.IMG file there instead of the GMAPPROM.IMG that was there previously? do you see anything else worth doing? TBH i'm still not sure what the 3D file is used for, or if i use it. i do use the 3d view when navigating. if i dump it, will i lose that, or is it just fine detail?
if i did use it, surely i would want the .40 version?

i do apologise for the endless questions. i though i was pretty on the case with computers, but garmin are just plain awkward. shouldn't updating a current unit, with mapping i've paid for be simpler than this?

you have certainly gone beyond the call of duty helping me out here

Another one for the collective minds esp. Cookie and Bumpkin...
I got a 4GB micro sd card and put it in the 660. Go to re-download the Maps in an attempt to put all of the Western Europe maps on the device.
Goes great until it - as expected - says there's not enough room.

Clickable link to buy a card from Garmin or choose another (smaller) section of the maps; but the option to insert an sd card is greyed out. WTF?
No doubt there is some extended drawn out process to achieve that? They dont make it easy, do they?
I'm expecting Bumpkin will have a 45 line easy-to-follow guide!

 

[Bumpkin]

Will try to keep it below 45 lines:

1/ Sounds like you've got as far as downloading the regular Western Europe region to the Zumo, this is a good start. Did you download all of Europe to the PC at the same time?

2/ If you did download Full Europe to the PC then you need to create a supplementary mapping file from this data for all the extra bits you want and put that on your SD card.

3/ Use MapInstall or Mapsource to select all countries not included in Western Europe. Have a look here for a list of what countries are in which regions, this was sent to me by Garmin in early 2011 and new countries have been added since so best to include all countries in your map-set selection and then remove those listed as being in Western Europe as you already have these on your Zumo.

4/ Mapainstall or Mapsource can then be used to write your new mapping file to your SD card. Ensure that you do send it to the SD card, not the Zumo, as there won't be enough room on the latter.

5/ You will need to ensure that the mapping on your PC is fully unlocked as you'll waste quite a bit of time.

Thanks Bumpkin - I'm following the concept, but...
Seems typical Garmin bollox where you have a simple box and what's required simply cant be done by what's in front of you.
Still haven't a scooby how to get the countries 'not' in Western Europe set onto the card...
