MDF and 'b' version radio

[unmanaged]

I have a #D43LRA7PA5BK (ABZ89FT3730) radio. I have a friend that does radio work for the local fire departments and he does have the radius RSS but I dont want him to hook the radio up if it might toast it as the models listed in the MDF are for a #D43LRA7PA5AK radio?

Will this limit the ability to program? What is the differences in the 'a' and 'b' models....

The radios are the same, but the "B" model has an engineering revision. Your friend might have to update his software.

I was just informed if an update is required that I would have to provide it?
What is the correct way of getting the update?
