i can see a software V6.26 on Furuno USA website for TZT2, is this correct? and if yes, i cannot see any details about what changes this offers, kindly assist.
6.26 was a software change that is for the TZT2BB. For the TZTL 12F and 15F it really only needs to be done if it is on the network with the TZT2BB (to keep them all at the same software level). Here is a direct link to the software history for the TZT2BB. I will ask the documents guy to add a comment to the TZTL history list to make it more clear. Thanks for pointing that out.
