Help with MK4 nav firmware downgrade

Hi gang!

I have v32 installed and want to downgrade so I can re-upgrade with modded splash screen....how many versions back do I need to go? I think I saw that v30 won't cause the downgrade. Any info appreciated...I've looked around and cannot seem to locate this info.

I use v29.1 and that seems to work as a downgrade which you can then subsequently upgrade back up to v31 or v32

Hey Phil,

Do you have a good download link for 29.1? I can burn it and do the work but I'm having a hard time finding a valid link to earlier versions than v32.

Thanks!

Mike
