I want to now what i need to do to update navcore it`s the version with 32mb ram and only sd card.

1. Remove your personal informations.
2. Check the tutorial section for some genral know how.
3. Pick any of my installers from the Navcore section and follow the instructions provided.
4. Check the latest map thread in this section and pick a map of your choice - make sure to select one that has a meta code.
5. Use FastActivate to to activate the map for your device.

I tried your universal navcore, remove everything from the sd card because device doesn`t have internal memory, put your navcore installed it ver for 32mb a then, maps with meta code and at the end fastactive, but when i start my device it froze on the welcome screen tom tom.
Help?

Download, unpack to the root of your SD and restart.

Was the only bootloader that still has a working link, otherwise you also use TT Home to update your device to the latest official Navcore to get a suitable bootloader.
But the newer Navcores won't work on a V4 bootloader, sorry I should have included the BL with the last posting.
