The seller must give you the Europe µSD card that works with your GPS hardware.
You bought the Europe mapping his home, it should work !
Otherwise, call the seller how to solve your problem.
Have you read the user manual, there is maybe a manipulation to do ?
bottlebank has written : I bought an sd card with Europe maps from the same seller, but its just not finding them.
The answer is here up in red, I think so really.
It's this one ?
