    Default Road disappears in my 3790T

    My 3790T is TW modeol and I save Europe map in my SD card.
    I disable TW map and move original TW map file in other folder.
    After power up, 3790T will only load Europe map, Europe 3D file and Europe DEM file.
    However, some roads will not show on my screen.
    If I do power-on again, lost road that on previous power-on will show, but another road will disapper.
    I don't know how I could correct this situaion.
    Please refer to below picture.
    In the rectangle, roads disapper.
    Bus statoin and store show the road is there, but not show in the map.

    I initial my 3790T, and go into diagnostic menu.
    However, I could only do testing in diagnotic menu of 3790T.
    I don't see any rest button or function in diagnitic menu.

    I will check later, if my 3790T still has this situation.

    Go to Map/Speed/ Speedometer/hold on xxkmh/Developer info/Nonvol statistics/touch the 4bars icon on the left/Clear Nonvol.
    this will delete all users data, backup your data before doing it

    Thanks. Catymag.
    I went to another mode, so I didn't do what you said before.
    I will test laster and check if I will get the same situation.

    Get another problem.
    After reset, my 3790T can't use address search funciton.
    It always show not map inside......
    I can only search TW address.
    However, Ponits of interest still work well.

    It's hard to track which step causes this failure mode.

    -------------------------------------------
    Update
    After re-unlock img file, address seraching function recovers.
    It means I need to unlock all main img file again.......

    Usual Nuvi are cashing unlock code to memory during first load with new unlock code. So you may delete unlock files but map still work normally.
    But then you do hard reset the cash will be clear too. So all unlock code in cash erased. If unlock files are present Nuvi reread unlock code to cash again after reset...

    I still get this program again.....
    When I was in Israel for business trip, I checked that some roads disappeared.
    However, I was not familar w/ Israel. I didn't do above clear action.
    After I came back to Belgium, I cleared nonvol again, and only installed Europe map.
    One day, when I check the road in Brussels, same situation appears......-_-"
