Beosystem 7000 Software-Difference 1.0, 1.1, 1.2, 1.3

i would like to buy a beosystem 7000. consisting of the cd and cassette player and the master.

master sw. 1.0

cassette sw 1.0

cd sw 1.1

now i wonder if an update makes sense or if i can use it that way.

maybe someone knows the differences between the updates. With software 1.3 with option 0, I certainly would not need it, because the system is in the living room and will always be operated by remote control.

thank you for your efforts ...
