Thanks for stopping by:
Unfortunately Nextar has chosen to NOT support it's GPS models with mapping or firmware updates.
It's kind of - you get what you get - for the low pricepoint
There is a company called NaviExtras that has picked up the software rights for some of the Nextar units....
But the X3 is not on the list of compatable ones.

Unfortunately, the only way to update the maps, or firmware, is to purchase a new unit.
thanks, XXXXX XXXXX of had that idea.
