And what is your problem?
It's very simple: connect your Becker to PC computer (I didn't try with Apple) and wait 2 minutes. Computer will show USB memory with Becker Content Manager software. Install it. And than you can buy new maps (firmware will be downloaded automatically if there will be newer. If you are updating your device less than 45 days since first use - maps will be for free.
