I don't hang out on the 2012 Forums so work with me
I have the 430N RHB software version 23.04.41
Theres a 24 Version ???
Anyways from what I understand there is a version 33.01.23 that must bee downloaded first ??? Sounds like a lot of 2012 owners where pissed with this update that they received in the mail because it changed there screen from black to blue (2011 owners already had a blue screen) but it did have some updates or firmware for maps
So from what I gather these updates will work for us 2011 owners with the 430N RHB even though they are directed towards 2012 Trucks ???
50.00.07 is the latest and greatest
Both found here for download
