Ah, no one ever named that device P

Lifetime maps/licenses/items do not last until the end of your life, but as long as the estimated lifetime of the device
It is the policy of all producers, understandable even though it is not to the will of consumers

If your device has original software, of course you will not be able to install new maps
Most likely this is the cause of the "problem"
Except that you may have missed the file structure, you do not have the appropriate license, which in the case of original software corresponds to - device/region/quarter

Becker software is based on iGO, so everything you need is in [Only registered and activated users can see links. ]
There are all the instructions, all the scenarios, all the necessary material there, no need for further questions
First, replace the software with the appropriate one, and after that you can put whatever maps you want. And, all maps can be placed on the card and be readable without any problems
