I'm trying to upgrade my 2007 Type S from the existing Nav version 4.55A to newer version 4.K0 which is what I received from Acura as the most recent. Both versions are part of the White disc series. The research I did said this was a doable upgrade, but when I try, it does the applicable download and shortly after reboot, I get a the message shown in the photo. It's not a DVD hardware issue as I was able to reset it and use my old disc again so I had the Navi back.

Anyone try this or something similar? I'd really like to have the latest release and have no interest in swapping out the head unit for something aftermarket.

I appreciate any input!
