    navcore /bootloader go 720

    Hi

    Recently i updated navcore 9.024 in 4gb sd card on my tomtom go 720. map version v850.2781 north america. everything works fine on sd using set x40 mode.

    But my bootloader version is updated to 5.5237. and it also got updated in internal memory. tomtom does not boot from internal memory, it only boots from sd card. if i take out the sd card. tomtom will not work. previously i had navcore 8.351 in internal memory which also got changed to 9.024 even i had install only in sd card.

    Internal memory boot load was 5.5120 which got changed and also navcore got changed to 9.024 map is v830.2323
    sd card boot is 5.5237 and map is 850.2781. navcore 9.024

    i have tried to find similar question in forum but no luck.
    Any Advice.
    Thanks.

    So you mean: install the navcore on the SD card which is NOT in the TomTom device at that moment?

    And is the bootloader automatically installed together with the navcore or should I install it separately?

    thanks in advance

    @Bertje,
    How is your TT-Go720? How did you fix it?
    Just want to start doing some work on my TT-Go720 too.

    My TT Go 720 with NC 9.041.1906, GPS v 1.20, Boot 5.5128 and map WCE 850.2800 works like a charm. Just copie the software and map (both found on GPS underground) on a SD card.

    However! Map share functionality is not working anymore with this NC, is this due the fact that this software is'nt original for a TT Go 720?
    Does anybody know how to fix it?
    I got the following screen (is in Dutch ) when a attached my TT to TT HOME:

    As yuriyggg correctly suggested.....format your internal
    memory.


    Then plug in USB - connect - allow TT to update to current Navcore.
    This process will take 3 cycles and yer back to a fully functional 8351.

    There really is no huge benifit updating to these 9.XXXXX's

    Actually, your device [any device] will work 100% just fine if you simply
    stick with current "official" navcores.

    Of course.....if you're one of those , I gotta have a 9.XXXX navcore, then there
    are plenty of threads dedicated to tutoring you towards a proper install.
