Thanks for your quick responses guys.

Just to clarify simonwedge's comment, the original HU-850 back lights worked and I assume they still will (thus I was considering using it's front panel). The cd stack just ate it's self.

I had read about the year compatibility software issue before buying the used replacement, thus a 2005 V70 same as mine was the donor car. My local Volvo dealer say yes they can remove the audio codes but there is no guarantee it will resolve the back light issue because the radio I have fitted still allows the steering wheel controls and all other features to work. They think I have bought a duff radio with the classic back lighting problem.

So as I see it there are two options 1) Try and carry out the project as described by the American or 2) swap the front panels.

Either of them sound not easy, more like open heart surgery !

Thanks for your continued interest.
