If you find a program to burn them to the USB drive...make sure you put them on separate drives!

I didn't try this but here is something that might work...http://www.isotousb.com/

Once the system recognizes the disc, the update will run automatically. All you have to do is press YES to update HDD and YES to go from xx.xx.xx to the next version.

the EQ is totally different . . . no dropping the Mid all the way down just to clean up the sound.
I knew the v50.00.07 would turn the screen background black . . . I decided to do them today. my RHB was on v23.xx.xx when I started so I installed the 33.01.23 and then installed the 50.00.07. . . . worked on the EQ coding


I have no freakin' idea what you guys are talking about, here. :-)

or the different firmware updates for the 430/430N. which is a separate unit from the 730N.
