Go720 and 2011 maps&NC

Hi.
I have a go720T with western Europe map (year 2008)
[TomTomGo]
DeviceName=TomTom GO 720
DeviceVersionHW=GO 720
RamDiskVersion=20090518
BootLoaderVersion=55120
LinuxVersion=315187
ApplicationVersionVersionNumber=8351
ApplicationVersion=9982
UserLanguage=Italiano
GPSFirmwareVersion=GSW3.2.4TT_3.1.00.12-C35B1.02

I would like to change the map with a newer AND (if possible) wider map (I need Country of Slovenia an Croatia)

From http://www.navitotal.com/forums/showthread.php?5502-All-New-Maps-870.XXXX
I see that W_C Europe 870.3406 is showed twice, once with the "2Gb" in the title and another without. But the lenght of both is stated the same (2.4 Gb). Which is the difference with the SAME length ?
Do I need to buy a 4 gb SDHC card or a 2Gb card ?

The official AND last match for NC + maps in GO720T is maps 870 3406 NC 8351
But the said thread, in the table at the beginning, is showing that the maps 870.3406 is compatible with cpseech, asr,IQ,alg, and that is working with many NC up to versione\u00ec 10.
Does this means that I can install the said map with any of this nc, and have the pair working with the GO 720 ?


Thanks in advance for the kind help.

1. A map larger than 2GB requires a 4GB card.
2. 870.3406 is a full featured map & can be used with navcore 8.2xx up to 9.2xx on the older devices.

1. The conclusion is that a 870.3406 NEEDS a 4Gb SD card (internal or external). Right ?
How can WCeur 870.3391 exist in the link above as a 2Gb map (first link) , and 2,4Gb map (third link) ? What is missing
2. The table above, reported clearly that NC 10.2xx was supported. Do you means that GO720 does not support NC 10.2xx?

1. Yes, if it is over 2GBs.
2. The compatibility chart in post 1 of the map threads clearly states the differences.
3. NC 10.xxx is not compatible with any device that uses TT Home.
