Map download advice

I have a TT 750 which is about 6 weeks old. I want to update the map and am being offered W&C Europe,Turkey & Russia, or four zoned maps. The W&C Euope Turkey, & Russia map is over 2gb but I have a 4gb sdhc card which has the current Europe map on it along with all the other files from the internal memory. This has left a bit under 2gb of free space, will the the W&C Europe, Turkey & Russia map of 2gb plus fit on this card? Does it overwrite the current map or do I have to clear the current map to leave enough free space?
Also is the detail on any given route on this map the same as the same route on the zoned maps?
Any help appreciated.

I have a device without card, so I'm stuck, but I think I remember reading that you can get the full map on a 4 GB card, but it has to be the only thing on it. The old map should also be on the PC as a backup, and you can copy it somewhere if you're worried about it.

It sounds like you were already running the map from the card, but if not, you have to set the card as the active memory before getting the v850 map with TT Home (again, I only read about that, as mine doesn't have a card).

Thanks for the reply. I have a back up of all the original files on my computer. What I need to know is do I have to delete the current map on the card in order to have enough free space or will the download over write the map.

No, the current map needs to be still on the card for Home to offer you the new one.
Home will then overwrite the old map with the new one, so space should not be an issue.

The best method is to do the upgrade using the SD card in a card reader, not inside the device - your PC will recognise the card as an external drive and TT Home will recognise it as a TT device, just as if you had the 750 plugged into the PC. Be aware that when the new map overwrites the old map, it will carry forward your POIs but probably NOT your Favourites, so take steps to cover this (e.g. convert Favourites to POIs). Anyway, do remember that a full Windows Explorer backup is your guarantee against things going pear-shaped when upgrading/changing anything.

Thanks for the replies. At least I know I can download the new map and have enough space. I have done a full back up but am having problems with my sdhc adapter which for some reason is not showing up when I connect to the computer. So it looks like a new one of those. So far I have not put on any POI or favourites as I knew a map update was due and would probably wipe some or all of them. Once the new map is on then I can put the POI etc on.
The other question I asked was, is the detail on any given route on the W&C Europe Turkey & Russia map the same as the same route on the zoned maps?

TomTom Home will only recognise the card as a TT device if it has the application on the card as well as the map. Copy the entire contents of your TT device onto the card, then load it onto a card reader and, as Dennis says, Home will think the card is the device itself and overwrite the map with the new version. If the card is big enough you will be offered the full W and C Europe, rather than the zoned version

The full and zoned maps should be the same - that's been the case with Europe and Regional maps previously, but this zoning is a new departure for TomTom, so I don't think anybody knows yet. I've seen no reports of any differences.

Gosh I just came here this morning to ask pretty much the same question as Home has just offered me new maps of western and central europe with russia and stuff added.

My Go 730 has 2Gb of memory and the current map is installed there but I also have a 16Gb SD card for music/audiobooks and photos.

Think I shall now spend some time with explorer and copy everything in the unit to my PC before I proceed - I have been relying on Home for backups until now.

Thanks - Dan

Andy, this gets me wondering...........

The Canada TomTom site is pathetic when it comes to map purchases; namely, you have a choice of North_America or Western_Europe and there is no way to select any other map or to designate a model.

But, you can designate a model on the US (and UK sites).

So, based upon what stuff has been transpiring the past couple of days here with how to get all of Western_Central_Europe offered, not just zones, by using a card reader and everything from a 720 or 720 copied to a sdhc card (maybe 8 gigs).....

Wonder if the same thing would work on the US site: Copy everything on the sdhc card. Use just a card reader. Request the FULL North_America map (normally only offered if, in Canada, you DO have a 930 unit) and say you have a 930 model so that the full (not the NA_2GB) gets offered.

Or, when all is said and done, if you do get the full map and then try to install on the sdhc card for the 730, you'll still run into 'not meant for this device' malarky??

Just musing here.....

Thanks for the reply DennisN. I have found out why my card is not showing in the card reader. Apparently the reader will only work with micro sd cards up to 1gb. So its off to the shops to get a new one that will work on 4gb and then wait for the weekend to do the download. Fingers crossed it all goes OK.

how old is your computer Richard. i thought nearly all computers in the last 4-5 years came with an inbuilt 17 in 1 card reader.

my 8gb card arrived this morning so in the process of transfering everything across from my 930 to the sd card.
one question i have is, once ive transfered everything onto the card and updated the maps 1) should i delete all the original files off the go and run it from the sd card or 2) delete all the files on the go and move everything back from the sd card to the go once its updated. or 3) move everything back from the card once its updated but just leave the western & central europe and north american maps on the card.

edit: here we go again.
coppied everything onto sd card. selected sd card as drive to update new maps.
go harddrive has 332mb free space of 3.74gb
sd card has 3.99gb free of 7.42gb
the new maps are 4.1gb so im still beeing offered zoned maps arghh!

time to delete everything and start again.
this time im just going to put the 2 map folders on the sd card and try it that way.

edit 2:
almost 2 hours and america map has got aother 15 mins to finish downloading and then onto the even bigger map to download.
