On a previous thread Sucro posted the following message to answer my question. I cannot respond on that thread for whatever reason so, I had to start a new thread. This is Sucro's message to me;
No no, you are wrong, you don't have to change GMAPSUPP.IMG to gmapsupp.unl, just copy-paste that file GMAPSUPP.IMG to your device-internal memory in garmin folder, or if you want maps on SD CARD, make folder Garmin, and copy-paste inside GMAPSUPP.IMG, use keygen from section software to generate key for your maps, for MAP ID use number 411, and that generate key copy-paste in NOTEPAD document, and save that document like GMAPSUPP.UNL (select for type file - ALL, when you save GMAPSUPP.UNL). You'll need CARD ID for unlocking maps on your SD CARD, you'll see CARD ID when you put locked image in garmin folder on your sd card, and put it in you garmin device, and go to tools\settings\ about, and look there for CARD ID, that ID you'll have to put in keygen 1.5 for generating unlock key...
Just follow described procedure for unlocking maps in thread where you can find JM keygen 1.5 for unlocking maps...
So to make sure I understand the procedure of installation I do the following
1. Download Jet Mouse' Key Gen
2. Find my devices CARD ID# by going to tools/settings/about on the device
3. Using Map ID 411 and the CARD ID# generate an unlock code
4. Copy and paste the unlock code into notepad and name it GMAPSUPP.UNL
5. For installation on the device navigate to the c:\Garmin folder on the device and copy and paste the GMAPSUPP.IMG file into it
6. For installation on the SD card insert card into the device or computer, navigate to it, and create a Garmin folder and install GMAPSUPP.IMG into it
If someone could please verify that the above procedure is correct I would appreciate it. If this is not the procedure please correct me.
