Espace JE audio

[Sommerby]

Hi there.

How can I see if my Grand Espace 2.2 DCI Priveligee has the grand audiotorium (4 x 45 W) or the audiotorium (4 x 15W).
The audio remote control is with a display and I got 4 wires for the handsfree installation.
I have installed a handsfree set but have not yet succed in getting the telephone sound into the audio speakers (I have read that this should be possible with the grand audiotorium). The radio indicates "Phone" when I use the phone, but the speakers only makes a weak whistle while I use the phone (So far I use the small speaker which is included in the handsfree set.)

Best Regards
Sommerby
