    To copy the individual files you've downloaded to the main memory you firstly need to know what's in there now and you also need to know how your current GarminDevice.xml compares to the one you used to download the maps, that's because if the XML now being generated by the unit is missing the unlock codes then the locked map may not work. If it has no registration or unlock codes in it you may as well just use unlocked maps on a card. Look for the codes right after '</id>'. This is mine disguised:
    Code:

    Baby steps: First let's dump the internal file system which is contained in region 48, and we'll get the current region 41 too for safety. Use a clean microSD, minimum size 4GB. In a Garmin root folder place sub-folder Updater. In Updater folder place one named 0972 [or if yours is MTK chip with HWID 1104 use that as the folder name]. In the 0972 or 1104 folder place Ldr.bin [it's just your boot.bin renamed, get it from the firmware using RGN_Tool]. Also in that folder place a text file named Update.txt with the following command:

    rrgn,41,1:/41.backup.bin
    rrgn,48,1:/48_backup.bin
    reboot

    You can copy/paste the above or write it yourself into a txt file using Notepad, but either way be certain there are no spaces before or after or extra carriage returns. Make sure you use the CORRECT firmware to get boot/Ldr.bin from because if you get it wrong your device will be dead forever if it's also without preboot available to connect to PC as it is with Mass Storage Mode.

    Place the card in the device with it off, plug it into a power source to turn it on and wait. It will take some time to dump rgn48 as it takes up much of the 2GB total size available for flash regions in 1xxx even if there's much less data actually in it than will fit [as it dumps free space too, so it'll be ~1.8GB]. When you have 48_backup.bin in the root of the card, open it in a suitable program. I use PowerISO:

    1490 Power ISO

    The above is showing the .System folder contents from an initial rgn48 dump of my 1490 a couple of years ago. Once you know what's in all folders you know what to delete so that you don't have conflicting or unnecessary files onboard with your new files. Probably not only Lane Assist function but also maybe JunctionView and even the Speed Limit Indicator may not work either. I hope you haven't lost TTS but i don't think so. Do a simulated route to see what works and if JCV does or doesn't work with your present map, 'cos if it doesn't there's not much point transferring the files.

    PS: I hope you are absolutely sure that the XML you used is for the same unit, if the Serial Number on the base of your 1490 and that shown in GE above match it's safe to use. BTW, for safety and anonymity never post your S/No or Unit Identification Number [UID] in open forum as zakon kindly advised you. I've disguised it in your first image.

    mine does have the ID (xxxxxxx) but no unlocked code. The serial number if the same on my navigation and the Xml file.
    I tested and these things work:
    - location.
    - Speed limit indicator.
    - TTS.
    The only thing doesn't work is Lane assist and Junction view. I do have the nuvi 50LM which i prefer to 1490LTM.
    I am studying for my test first and will give it another try later on. truly appreciate your help, This is the best forum i ever joined.

    Ok, good luck with your tests. Post again if we can help later. Because you've lost essential data and your 1490 is now identifying as a basic '14xx' without advanced features you've lost LA/JCV [maybe BT won't work either] and also with the codes missing from the device you won't be able to use GE to update it with the current GarminDevice.xml generated by the unit itself now. Thanks for the compliment about the forum, we just like to try to give as much help as possible to our members.

    Map codes are stored in MyGarmin, in my experience he can update maps anyway. Model loss shouldn't affect lifetime map updates, at least it doesn't in my 3790.

    That's good news for OEM LM devices. I have a 3790 which has a separately purchased Lifetime map subscription. I experimented some time back with it, where i removed the codes by deleting the xml file and doing something which i won't mention in open forum [you know what ], when the xml file was recreated by the unit on boot and it was connected to GE it saw it but refused to update it and reported 'no maps are available for this device' or similar. I restored 'you know what' and everything was back to normal. I'd assumed that missing codes from the xml would result the same for either 'LM' whether factory original or purchased later, but i'm pleased to hear otherwise at least for factory LM. Thinking about it again in light of your experience and explanation Caty, it kinda doesn't make sense about the codes being absent from the GarminDevice.xml being the problem, i have an EU 710 [no codes in it's XML] which isn't even being recognised by GE at all [much like frankngu's 1490 isn't either], and i was told that 'you know what' was done to the 710 [no restore is available, happened before i got it]. Maybe older and newer devices aren't treated equally when 'you know what' happens or it's dependent on whether the LM is OEM or added later.

    He can try to add missing features with [Only registered and activated users can see links. ] may be it works
    Maybe, but i don't think so because all features are already present in the firmwares for 1xxx. Features such as SLI, LA & JCV are enabled and disabled by the device's rgn16. The logo splash we flash to junior devices to enable 'missing' features as you know is the one from 1450/1490 which he already has in rgn16 [D1340-50]. But it won't hurt to reflash it to try of course, perhaps it's been compromised as well as rgn41.
