Hi George and welcome to the forum.
What a lovely system you have, I have one myself.
The Beo4 can do anything you want from your 7000 except setting up timers, and it is a bit tricky tuning radio channels, though not impossible.
I have to let you down gently about RDS.

The only advantage with the RDS is that it shows in a small display on the Beolink 7000, which channel you are listening to,
not on the system or the speakers. Of all the fantastic features this system has, RDS is the least useful.
If you bear with me for a moment, I'll find the thread which tells you how to tune radio channels and post it on here.
