A4 CD player lead ???

[spaarky]

Guys - anyone used a panasonic multichanger cd unit (out of another audi) in a 1998 A4 ? Apparently a converter lead is required (plugged into the stock audi lead in the boot) to tell the stock audi concert head unit that it's dealing with a panasonic cd changer - does that sound right ? A Peripheral AUDPAN98 lead has been quoted as necessary, but ain't cheap, or even readily available - any ideas ? All comments welcome & much appreciated

My dad's 98 A4 has been using the panasonic changer unit for a year (with a Peripheral lead - green, approx 12" long) before it suddenly died while in use - trying to work out if it's the unit that has died or the 'converter' lead. There's power to the changer unit, but the head unit won't recognise/do shit & have been told that using a panasonic unit in an audi needs a 'converter lead' so that the head unit will work with the panasonic cd changer - anyone come across this before, or is it just an excuse for car audio firms to screw unnecessary cash out of us ?
