Unlocking with gimgunlock or Fast img unlocker or Unlocker Alternative doesnt remove search in the .img.
Installing .img in MS with GmapTool removes search in MS and the related created .img in MS will have search removed.
Use Basecamp to display .imgs in your pc. Copy the .img in the SD/Garmin/.*img and start Basecamp.
To have a map in gps (with search enabled) just unlock and copy the .img in gps in the right path.
