RNS-E to Symphony

[bennyball]

Can anyone tell me what is needed to get the symphony stereo working please?

I previously had a RNS-E unit with Bluetooth, MFSW, SDS high etc, but after a scummy individual decided to take what wasn't theirs I'm loathed to fork out for another.

I've bought a cheaper symphony unit but when I plug it in the unit seems to get power but there's no response on the screen.

Any help appreciated, thanks
