I just bought a 1998 Renault Safrane and need to replace the faulty
CD/Radio.

Do I HAVE to get a Renault replacement of can other manufacturers
units be adapted to work with the Renault Steering wheel controls and
dash display ?
You can use other radios but they need additional leads to make the controls
work sony and alpine being 2 companies in i no supply leads. Fitting isn't
easy though
