In case of update directly via mobile u must need WI-if, which is not available in all region. Why I can not use a mobile network if data plan is activated?
in phone u can pause the update and u can continue later, but in nokia suite u have to continue still it complete.
I have noticed that in PC the whole map data first download as Zip file in temp directory and then transferred in phone.
It will be more better if it can be downloaded first and then just connect the phone and transfer it to phone, and the download can be paused.
