Could anyone offer any advice/suggestions?

Try connecting both power feeds from the head unit (red and yellow) to
the red cable temporarily. If this results in the JVC working with the
ignition on, you've blown the car fuse in the permanent live feed.

I've tried with both leads connected and get the same result in each
case. If I re-install the original Blaupunkt head unit it still works
fine - i.e. turns on and off with the ignition key. This presumably
indicates that the power feed is OK from the ignition switch?

The fact that the supplier found no fault with it indicates that the
problem is with the connections in this vehicle, but the fact that the
other head unit works fine eliminates alot of the potential causes.
