They are physically identical (other than the decal), yes. Functionally, the v3 firmware is a huge improvement over v1 (including much improved tracking). There’s really no reason not to update your firmware. 

Can the v3 unit make different sounds than the v1 unit assuming both units are on v3 firmware?

It's massively improved with loads of new amazing features (but still can be used exactly as before). Have a read of the information in the first two posts of this thread. You should absolutely update to it! It's a free and relatively-easy firmware update for v1 owners.

So the FI v1 and the new v3 are identical except for the decal? Same tracking or is there a difference?

i have the v1, is it worth it to update to v3? sounds like besides improved tracking everything else is identical?
