Ok folks - installed 3.0 and verified through the Avic AVIC-F700BT unit. Thanks Terron!
However, the main reason for upgrading to 3.0 was for me to get my steering wheel to control the presets. Unfortunately it still doesn't seem to work. Any idea why? Do I need to set it up somewhere through the unit?
The start-up time seems to take the same as before.
Additionally, I don't really see any other visible difference between the 2.x version I had before and the 3.0 unit i have now.
Finally, I did have to reset the colours as well as all my settings, although I did do a back-up.
So any other thoughts?
