Hi Garry,
As you can see the latest version is "
22nd October 2021".
Unless you are technically competent at "flashing" CD Cards with operating system software (in which case tell us here and we will guide you through doing this for the B2), I would suggest you purchase a
I believe your B2 will have a little SD Card that sticks out of the right hand side (mine is of a similar age and has this). IF this is the Case then you need the top SD Card, IF there is no card sticking out of the side
then your card is internal and yo will need to order the lower "Micro" SD Card.
If you card is internal then you need to take the back off the B2 to install it as described
here (it is not difficult to do).
Once you have fitted the new SD Card, power the B2 up and using the Front display and the Round knob - go through the Menus thus:-
Main Menu > Settings > Web Upgrade
This will ensure that you are on the very latest release (the one on the card may have been written before the latest version came out).
Your B2 will then behave and have all the functionality of a new Brennan B2.
