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.
