NAV Problems with V29 software update!!!!
 

I've just updated my system with V29, and now, my screen just shows a message that says "Please insert key CD or version 17", I don't know what is that, and I can't do anything, the radio works, but in the screen just appears that message, what do I do?????!!!!!!

there should be more than enough info in the Navigation forum...
i would say that you need to re-burn the disc...
