    You don't need the 2010 map and it could interfere with the new map so just remove it. Correct naming would be 'gmapprom.img' not 'gmapprompp.img' in any case.

    "gmapsupp.img" or "gmapsup1.img" in "Garmin" folder is only one worked way for SD with 255w!!!
    Love your wife? Buy yourself a GPS for answering to her favorite question: "Dear, where are you?".

    No mate, he's referring to his 2010 gmapprom on internal memory which causes the 'can't unlock map' message which is why i said to remove it. He's said the 2015 map on his SD card is working ok.
