Hi i have a 1998 series 2 with stock Harmen system , i want to replace the stock radio for a Pioneers single din, had a look at the old unit and connectors are standard ISO connectors but i have plugged in the pioneer and nothing, no sound, all powers up ok , finds radio channels but no output.
Guess its to do with the amp? anybody solved a similar problem??
If i get it working i will buy the steering wheel adaptor.

Thanks
 
I'd love to know the answer here.. I've just pought a disco td5 but the amp under the seatd been removed.. Can I bypass it ?
 
Following on from what Discool has already said, in both the Harman Kardon and the high-line ICE systems, the amplifier under the passenger's (left hand) seat drives all of the speakers (3 in each door and two in the tailgate) so a straight bypass might require a bit of working out of the speaker wiring.

The amplifier unit has a main 12 volt supply to it, as does the CD autochanger but there is a +12 volt "enable" signal from the head unit which is used to switch on the audio amp, the CD player and the two aerial amplifiers; medium/long wave and FM. The enable voltage leaves the head unit on pin 5 of the "power" ISO plug.

In after-market equipment documentation this connection is sometimes referred to as accessory wiring and suggest that it's used for automaticlly extending telescopic aerials.
Without that voltage the amp won't switch on.
