In answer to Indra W's original question re: The USB Stick
First let me say this is NOT the method to be used to update the maps for the i30. So if you want to experiment with the following explanation, do so at your own peril.
But after a lot of web searching, what I have found is a method used by other car models to update their maps via a USB. It is reasonable to assume that the Hyundai i30 may use the same principle sometime in the future. A broad overview of the common process seems to be as follows:
1. Download and install software called SyncTool, which is specific to your car, onto the USB stick
2. Download and install software called Naviextras Toolbox onto your PC.
3. With the car's entertainment head turned off, put the USB into the entertainment head and then turn it on.
4. The entertainment head will (ought to??) boot up from the USB Stick.
5. You will now be in a different operating system (SyncTool) and from the options provided, copy the entertainment head's software/data onto the USB stick. This could take a long time (50 minutes??) and the process must not be interrupted.
6. Take the USB stick over to your PC, and by using the Naviextras Toolbox, update the maps data component on the USB stick (You need to have an account and it will cost for the update).
7. Take the USB stick back to the car and, again, boot the entertainment head from the USB stick
8. From the options provided via the SyncTool, update the entertainment head's software/data from the USB stick. Again, this could take a long time and must not be interrupted.
At this point in time I can't find any SyncTool that is specifically for the i30. I am guessing the difference between the cars / models is contained within the SyncTool's 'Manufacturer.ini' file. In one that I downloaded the contents read
id="Zenec_Synctool_C9"
I suspect if the
'id' is not correct for your car's entertainment head then the update process won't work. AND you could corrupt the entertainment head's installed software.
However for those who would like to know a little more, here's a sample site to look at:

There are other car sites with similar SyncTool instructions.
