@miroslavbl,

Again I repeat myself the Nuvi 2559 firmware is not of the new STD. It still has the unprotected system.
That means you can put any maps you want on the 2559.
That means you will have to get unlocked maps which are not here on this forum.
Or buy what you need in the way of maps.

NO patched firmware is needed.

Did you uninstall the the Garmin USB drivers and reinstall them????
Do you have something blocking the USB port from accessing the Garmin???

Did you contact Garmin with your problem?

Have had this problem or is this something new that has just started?

Is the unit second hand or did you buy it new years ago???
