Thread: patched mapinstall limited to 4 gb only not full region -Europe ntu

I'm a bit lost as to why you want to use MapInstall to install a Garmin .img file onto your HDD anyway. BaseCamp can see and work with the PC Installed data from the .gmap folder and you certainly can't use an image on a HDD/SSD with your device which can only use an inserted microSD (FAT16) or microSDHC (FAT32). FAT16 is limited to individual file size of one byte less than 2GiB and FAT32 is limited to one byte less than 4GiB. These are not Garmin's restrictions, the size limit is because of those File Allocation Table limits on file size. Your device cannot use either NTFS nor can it use exFAT (Extended File Allocation Table) both of which can have file sizes larger than 4GiB as said. By the way, GiB is Gibibyte which is the (original) binary form of Gigabyte. These days GB (Gigabyte) is usually referring to the decimal form. There are 73,741,824 bytes more in a Gibibyte over a Gigabyte which is over 7% difference. FAT limits are binary (factor of 1024) as used by Microsoft, not decimal (factor of 1000) as used by drive manufacturers.

If you do the maths, it means that in binary "4 Gibibytes minus 1 byte" is 4,294,967,295 bytes which in decimal is 4.294967295 Gigabytes. Hence is is easy to get sizing confused when it's not clear that we're talking binary or decimal.

Now, about your concern below:

so how can i hv full region of Europe ntu as its 4.2 gb so i can use voice command with it
voice command works with full region maps only

Simply use MapInstall to make 2 separate .img files for all of Europe as already suggested. Provided ALL of Europe mapping is available ASR will work, it doesn't have to be in one file. You can even have one file on the device and one on an SD if you want, provided the two .img files have every single map tile between them.
