    Default Bluechart G2 Vision in two nautical gps.

    Hello everyone.

    [Login or Register to remove this advertisement]

    I have two nautical gps (GPSMAP 741xs and echoMAP Plus 74cv) with the same cartography, VSA001R, but with very different results between both gps.
    In the 741xs all versions of the VSA001R G2 Vision (v13, v16 and v17.5) and G2 South America HXSA500L work, while in the 74cv it does not allow me to unlock any of the maps listed.
    I tried to unlock them with the * .unl file (JM-KG-v1.5) and it did not work, I also tried with gimgunlock and it did not work either.
    Does anyone know what else maps can be unlocked on the echoMAP Plus 74cv gps?


    Information used with the JM-KG-v1.5:
    HXSA500L v14.00 FID 2644 PID 1 Region 4.35
    VSA001R_v16 - FID 2462
    VSA001R_v17.50 - PID 1, FID 4054, region 1.10


    If someone can help me, I'll thank them very much.


    Thanks in advance.

    Hello again. After doing some tests on the echoMAP Plus 74cv, I realized that the messages are dissimilar depending on whether the Bluechart G2 Vision files are locked or unlocked.
    If the img is locked using the correct data in the KG the answer is "the map can not be unlocked", however, if the img is unlocked with the gimgunlock, with or without *.unl, the answer is "the map can not be authenticated" and it sends me to read the manual.
    In conclusion, the new gps seems to have another unlocking system that does not match with the traditional way that we have been using until today.
    Does anyone know what the new unlocking method might be?
    Greetings.

    That’s what a 64 series says about a correctly unlocked map file before it’s firmware is patched.
    I suppose the one that says it failed authentication is a newer GPS that has signature checking or what have you,
    and needs firmware patch (if there is a patch for that model).
