How do iupdate my icn330

Remove you sat nav from the car (I am presuming it is not factory fitted) attach to your computer via a USB cable there will probably be a USB mini or micro socket on the sat nav, you should have been supplied with the correct USB cable when you bought the unit.
Once you have connected your unit to the computer go to the sat nav manufacturer website and select products. Go to your product and look for downloads or updates.
Also check that the sat nav screen isn't asking you questions to communicate to your computer. Sometimes you have to agree that the unit an talk to the computer or nothing will happen.
When you have found the relevant update save it to your sat nav unit being carefully not to unplug the USB lead untill you are completely finished.
When you restart your sat nav it should be up to date.

You can update mapping software on most sat nav units to take into account alterations to the road network. Either from your PC, in the case of portable sat navs; or via your phones GPRS connection, in the case of phone models. Always check the level of mapping that comes with your equipment in the first place. Is it up-to-date?
. Every couple of years Garmin will release a map update, which you can get on DVD or download - you've got to pay for it though!
