Hi,
I am living in europe and i just ordered a tsu3000 in the us beacause of a lower price.
I read carefully the posts in this forum and the detailed article, and if i am right the differences are:
1 - the pre-progammed codes wich are specific for the us.
2 - the rf frequency wich is 418 MHz for the us and 434 MHz for europe

My questions are: do a firmware upgrade modify the codes database?
can i use a 950 firmware upgrade on a tsu3000 ?
is the rf frequency a software difference or a hardware difference?

Many thanks in advance for your reply.
