Do the 2008 Toyota's and Lexus' have the same Nav?

I've created the hybrid disc but my 2008 Lexus will not load the 5.1 firmware from the disc.
If the car is on and I swap the discs, the system can read the maps and POIs from the hybrid disc so it seems the disc is sort of working.
If I remove the fuse for 10 minutes, the system doesn't load the disc. When I put back the original 7.1 disc, it loads the 7.1 firmware and continues working.

Has anyone had their 2008 load the 5.1 firmware? Is the 2008 unit still a Gen5?

thanks.
