I think the approach should be to use the v26 code and figure out how to change the options.

There are a lot of options in the code such as OFF Road, Taxi Route, car rental mode, ect.

I have made new installation disks with the V26 code in the following configurations.

None of them loaded the perspective mode

All V26 files, loader.ini from V26.09

All V26 files, bsw2 from v26.09

All v26 files, lowboot from v26.09

All V26 files, navboot from v26.09 This one was odd, as the software said loading 00, then I stil had the v26 ==bmw== logo and 6.0 on the settings menu and no perspecive mode

This makes me think that the navboot file is only loaded if "needed"

I have gone thru the tioarch.tar files and they seem identical

I think the smart option would be to find the switch to turn on perspective mode
