Okay, I am way confused with map update. It might be because I read a lot of the earlier posts which are now obsolete. I have a 755T and I downloaded the files that apply but I am not clear as to what/how I should use. The following are my questions:
Q1: Is there a limitation on the SD card size that can be used? I was going to use an 8 GB card but I am not sure my 755T will recognize.
Q2: I was hoping to put the update on an SD card so as not to affect my existing configuration. From the tutorials ([Only registered and activated users can see links. ]), it appears that once I use the SD card, the unit will not work properly if I remove the SD card. Is this still true?
Q3: Some of the tutorials reference Basecamp, MapSource, MapInstall and HomePort. It is my understanding that some of these are no longer supported from some of the threads. For the unlocked images, can Windows Explrer simply be used? Someone with more experience may want to clarify the obsolescence issues upfront in some of the tutorials and indicate the current preffered method.
Q4: I took the original MapSource data and used one of the unlockers (NOTE that GarminUnlocker.exe which uses the .tdb file did not work for me) as Mapsource and MapInstall were saying it was locked (yeah duh, I realized that afterward). I ended up using MapInstall and put on my 8 GB SD Card. I see it created a single file (gmapsupp.img) and that's where the duh moment kicked in (unlocked map is already this file). I have not put SD card in my GPS yet. Could I have simply copied the unlocked gmapsupp.img file directly to my GPS? I don't currently have a gmapsupp.img file on this GPS and I don't think there would be enough space.
Q5: From the file structure of my GPS unit, it looks like the GMAP3D.IMG file goes in the Garmin subdirectory since it is already there. A quick check of my 755T does not show these files at all:
How/where would I put these files?
Q6: From what I see, can I simply copy the gmapsupp.img and GMAP3D.IMG files to the Garmin directory using Windows Explorer and consider the update complete?
Sorry for my confusion, I may be overthinking things.
