      The best thing to do is try new ones but always backup your original.

        Only concern I had was that I have read here that one can brick the TT if wrong core is used - hence my question about a "safe" one to upgrade to.

          You can safely use Navcore 8412.1236, its not the core that will brick your device, its the bootloader, so if you remove the "system" file from any Navcore before installing it you are safe. If it works OK then dont change it. READ MY POST IN THE NAVCORE TUTORIALS ON BOOTLOADER VERSIONS
          You can safely use bootloader 5.5015 or 5.5128
          Open your device in windows, open the ttgo.bif file with notepad, see which bootloader you are running at present

            Many thanks for that. I am using 5.5106. What are the advantages for the upgrade to say 5.128 apart from newer menus I think? If I put the 5.5128 "TTsystem" file in the TT root directory, will it need to be pathed with Easy Activator?

              Before I spend the money, will 5.5106 use SD greater than 2gb?

                YES, 5.5106 supports 4Gb.
                Also do not confuse "ttsystem" with "system" ("system" is the file that re-writes the bootloader eprom)
                AS I REPLIED TO YOUR POST BEFORE, READ MY POST IN THE NAVCORE SECTION UNDER BOOTLOADER VERSIONS

                  Thanks for the help. I am now on:

                  TomTom One V3, Bootloader 5.5128, Navcore 9.053, GB 850.2820.

                  Only question I have is; is this the most suitable combination?
