For those of us in the U.S., you should contact Panasonic U.S. (Eddie Williams).

He said installing an upgrade not distributed by Panasonic U.S. could hurt your warranty.

The changes came from the factory and are the same no matter where they come from but
why take the chance with possible download problems, when he will send them to you and if you have a problem he is there to help you with no warranty worries.

When I receive the 1.5 I do not intend to install it until I find I have a problem.

Not broke.........don't fix it!
