Thread: Garmin GPSMap 78SC

HomePort like BaseCamp will see both locked and unlocked img files. Seems like your other maps/charts that are recognized by your device are either unlocked or are official img files unlocked only to the SD they were purchased on. However maybe HXUS039R is not unlocked. You can try unlocking it with gimunlock, you'll find a link behind the spoiler in initial post here: [Only registered and activated users can see links. ]. You can also check if the img files are locked or unlocked using GMapTool:

Hi, I can actually see HXUS039R in Homeport using a micro SD card and an adapter. This is the 2012 version. I just downloaded the 2013 version which is supposed to be unlocked.
We'll see. The other thing that I'm trying to do is combine a bunch of gmapsupp.ing into one gmapsupp.img. I tried doing it in GMap Tool. Said there were errors. I have Garmin US LakesVu HD v16.50. The Dir contains gmapsupp.gma, 3kb, gmapsupp.img 10kb, gmapsupp.unl GUPDATE.GCD 832,569kb, LakeVu100C.img 402,320kb plus 14 more img files with different letters after the LakeVU. I'd like to get all the img files combined. Homeport will show one img file at a time. Thanks, Jim
