Having finally let the old girl go, I'm selling its stereo (Sony MEX-5100BT, brilliant unit) complete with ISO harness and patch lead for the steering wheel controls.
There's a local guy interested, but he knows nothing about these matters, except that he wants a decent unit for his 75. I told him it was a 10 minute job to fit (was for me), but have just learned that not all 75s have ISO connectors behind the dash, and I don't want to mislead him - he's paying somebody to install it.
Is there any way of knowing in advance which kind of harness he's likely to have?
Cheers
