Hello, any progress to unlock the browser? I have not achieved anything. I got the CID of the SD via adapter connected to an android phone, and I wanted to make a card "goldcard" to see if he recognized the navigation unit .... but nothing . Talking to a person working in Windows CE systems, told me that the hidden partition can be the "rom" browser, usually do this in such systems. But I have not been able to access that partition, or from Windows, Linux or Mac Moreover, the new cards in 2014, resized, 8Gb now ... so if you ever want to upgrade our cards 4Gb through navteq (officially), I do not know how we're doing ; we're going to get to buy a new card with the maps. It is proved that the size of the card information does not take the 4Gb.
