I have got my software fix working... (but not quite tidied up yet)

I should be able to put together an upgrade file which will install a new kernel and a new root in /dev/hda2 with an init that will detect the presence of a tuner and override the power connection detection so the player software believes it is in the car...

Seems to work fine on my system... Do you have a tuner in your car...? I will try and put together an upgrade image you can try if you like..

Cheers
