I have been playing with the IID tool since I got one shipped to me a week or so ago. The GAP team was able to release some new firmware since I reported to them that the new version would not let you load the NAV ON MOVE firmware to unlock the navigation controls while moving the vehicle (otherwise you cannot input new addresses or configure settings, which is super annoying if you're on a long trip with a codriver).
Well I did the flash today of the NAV system and had no issues, BUT my nav remains locked when I move the truck. What gives? Anyone implemented this on the disco 3's?
I have emailed GAP as well with this issue so hopefully I'll find out sooner or later. Chime in other IID tool users if you've done the flash.
