The Application and Audio CPU revs are the same as what I had started with before the 33.01.23 update (prior to this one). I'm not sure if you have to update to that first or not before going higher?? I wouldn't think so but don't want to steer you wrong. There was another update inbetween that I did not get, the 43.xx.xx and it worked just fine jumping over but again, I'm not sure what to tell you. Certainly don't want you to mess up your radio.
I would go to the other thread and ask or PM xsdbs about this. He is up to date on what is going on with these radios.
Look for post #46 to find xsdbs.
I don't believe the update will change the Sirius and Gracenote revs.
