Problem with trying to use CCD GOLD card on Echomap Plus 44cv

**Pedro Henri** · 15th February 2019, 02:17 AM

Hello, this is my first post in the forum. I would really appreciate your help. I own a Garmin Echomap Plus 44cv V5.20 and here in Brazil besides Bluechart South America, I use the CCD GOLD PLUS (MapID: 12270) in another GPS. I'm having a hard time making Echomap recognize this letter, I have the original 25-digit code, I've already tried unlocking my own letter and I can not make Echomap recognize it, always when I start the device it displays the message "Can not unlock the map. " What can it be? Does anyone know of any way to make the device recognize the letter?
I read something about generating the 25 digits according to the MicroSD serial number but I do not know which program can be done this.
PS: Forgive my English, I already tried the program JetMouse, GarminUnlockerAlternativev8.0.1, however, I think it's just missing some detail. Thanks in advance. This forum has helped me on several occasions.

Garmin Echomap Plus is not read any map without the Garmin original signature (gma). But know you can patch software in the device as I heard.

It depends, I am not totally sure of this information. It may not work with the software updated in the last V. 7.50. However, a colleague has the same device, in the same version of the software and has the non-official letter of Bluechart, only works on his device, when I insert my GPS does not work, who created, associated with his SD card, then reads letter unlocked or modified. And I think it's something like that that is missing to make the GPS recognize the CCD Gold, just do not know how.

Yes, I managed to make the map run on another Garmin device, I came to the conclusion that only unlocking or applying a patch in the software will enable it to run unlocked maps. Could you help me about it? At least show the way, the device is the Garmin Echomap Plus 44cv Software version 5.20
