Bro joelton12345,forget about the rest of details, lets start by solving the most important detail ... did you or did you not manage to view the /system file. You need to be able to view the /system file and then we take it from here. Depending on which Microsoft OS you have, please google on how to display hidden files.

I have found out already, actually beside tick the hidden files function, another is not to tick the "hide protecting operation file" that why I only found out this, now I can view already. so what the next step? if I move the msm map out from garmin set, will it cause junction view malfunction? next time if update only at sd card, the junction view will appear again?

If yours is localized set, my advise is to leave the preloaded Garmin NT and MSM NT map files there as any map update will override these files.

Just load the MFM file in SD card will suffice

But if you opt to move the both files, then move them to SD/map directory. Likewise JCV files in main memory should move to root directory of SD card

how I know will move the junction file together? the seller told me if move the junction view files will unable function?

Run Nuvi in simulation mode of "known" junctions where JCV shows ...

no, what I mean was if I move the MSM map to sd card, should I move the junction view files together? what is the junction view files name? will cause junction view malfunction？

JCV files are coupled with the maps and must be moved together. If your set is a localized set, then you will have 2 preloaded maps (gmapprom.img and gmapprom1.img) in your \.System folder in the internal memory and 2 JCV files in the JCV subfolder of the \.System folder.

You can move the 2 maps to your SD card and put them in a \Map folder and the maps will work even without any name change.

But for JCV to work, from my experience, the map must be in the SD card's \Garmin folder (and not \Map folder) and the correct JCV file in a \JCV subfolder of the \Garmin folder in the SD card.

Your problem is identifying which JCV file goes with which map. To overcome the problem I put all JCV files in the \JCV subfolder regardless of which map I am using. The only downside is that they take up some space. Garmin usually names each release of JCV file differently from the previous so unless you know which file is for which map, your JCV subfolder may contain a lot of orphaned JCV files.

One very important consideration. If you move the map to the \Garmin folder, for it to work, the map must be renamed to gmapsupp.img. Your problem is knowing which map is the one you want in order to rename it.

look like very difficult to do it, took time to consume the statement jason, me also blurr. scare to move it to sd card

Don't be put off by the number of words.

I have given you more than you need. I have explained why instead of just saying do 1, 2, 3 etc. This is to save you time in not having to write again for explanation.

Actually very easy to do.
