I was looking at the new Platinum Tundra this weekend and I noticed the nav menus are updated with different fonts and possibly new features. Is there anyway to upgrade the firmware on my 2007 nav unit to take on newer nav unit updates?

I am using the latest maps but did not notice new fonts....maybe using the old loading 5.1 file prevents these different fonts.......perhaps someone else who has used the 9.1 version and the earlier versions can comment...

Did you disconnect your battery before loading the new disk? If not, you might try that and see if it loads the new features.

I have a 2010 Tundra CrewMax Platinum and had your same old nav in my lexus, no you cant upgrade your disk to the new nav - its a different OS
