*Garmin Mobile XT Free Basemap

*Garmin Mobile XT Support Files (voice navigation files)


2. You will need the map file (i use malaysia-singapore free map from MFM, file name: gmapsupp.img)


3. You will also need the keygen (file name: garmin.exe)

Or search for Garmin Unlock Generator 1.5.

*Before I begin, let me highlight some problems i encounter when i installed garmin on my phone. It just wont install (expired certificate). If you encounter such problem, no fear, its a firmware bug. all u need to do is back up ur phone to ur sd card, and do a hard reset (enter *#7370* and enter lock code). After hard reset, you will be able to install.

STEP 1: Connect your phone to PC via Data Cable in Mass Storage Mode

STEP 2: Run the GarminMobileXTforSymbianS603rdEdition_50030.exe you downloaded earlier. Select the ‘Mass Storage Device’ which is your memory card in your phone.

STEP 3: Run the GarminMobileXTFreeBasemap_4xxxx.exe you downloaded earlier.

STEP 4: Run the GarminMobileXTSupportFiles_4xxxx.exe you downloaded earlier.

STEP 5: Copy the map file gmapsupp.img you downloaded earlier into your phone, under the directory ‘x:garmin’ where ‘x’ is the drive of your Mass Storage Device (your memory card in your phone)

STEP 6: Using the safely remove device function of your PC, remove the data cables.

STEP 7: Run the File Manager application in your phone

STEP 8: Scroll to ‘E: Memory card’ and scroll down. Run the GarminMobileXT.sis file. This will install Garmin on your phone. note, this is where i encountered the ‘expired certificate’ error. If you do not encounter this, ignore this line. If you do, do the hard reset.

STEP 9: Run GMobileXT from Apps.

STEP 10: This is where you see the Garmin Spash Screen, and select Agree

STEP 11: Your Garmin might prompt you to enter product code etc.. or start searching for external BT GPSr. Click cancel to get to the main screen

STEP 12: Go to Tools (circled in yellow) –> Settings (circled in green) –> Scroll Down (circled in blue)

–> Go to ‘About’ (circled in white)

STEP 13: Copy down the Card ID on a piece of paper (my screenshot doesn’t show card id because mine is already unlocked)

STEP 14: Now, run the application Garmin.exe and enter the card ID (1), click on Generate (2) and copy (ctrl+c) the device unlock code.

STEP 15: Start the application ‘Notepad’ and paste the code there like this, and save the file as SW.UNL (Please take note, when you save the file, you change the file type as ‘ALL TYPE’, as illustrated below, in red.

STEP 16: Now, reconnect your phone to your PC via Mass Storage Mode. Paste the SW.UNL into your x:garmin folder.

VIOLA!! Welcome to the universe of Garmin Mobile XT.

  1. I tried through first time and it didn’t work. I turned out that the UNL file generated with the k*gen was no good. I made another one, and it worked.

  2. It’s too cool and beautiful to develop and motivate, build up character.This is the coolest website and stories that i have ever read…its useful for me as im a lecturer and always motivate my students with these publised stories…thank you …and waiting for plenty more…

  3. Together with everything that appears to be building throughout this subject material, a significant percentage of points of view are actually relatively exciting. However, I am sorry, because I do not subscribe to your whole suggestion, all be it refreshing none the less. It would seem to me that your comments are generally not completely justified and in fact you are generally yourself not really thoroughly certain of the argument. In any event I did enjoy looking at it.
