Mazda Cx9

[jumpin jimmy]

hi
I have a 2014 mazda cx9 that has tom tom sat nav on an sd card installed from Mazda factory.
If I want to enter an address it tells me no city known, this also happens when I enter a post code.
The only place it knows is our home address and it will take me home from anywhere.
The map shows where i am whilst driving.
But it won't let me search for an address..
Any help would be great.
I just connected my sd card to my computer and upgraded everything and put it back in the car but same thing ??
Help please.
thanks
