I did this not long ago for a friend.
I found it to be a real pain in the
!
What I ended up having to do was log into Humminbird. Create an account, registar his unit, and then there is a
program and instructions on Humminbirds web site.
In all honnesty, after going through all the registration crap, it was actually not bad.
I’m sure there are other ways out there but after spending quite a bit of time searching, this is how I ended up doing it for him.
If you got a new Bird, it probably would be a bad Idea to registar it on there wed page anyhow.
Good luck.
This is I do know, it’s way easier to go from Bird to Lowrance, that’s for sure. Done that many times and in a few minutes with ease!
