I finally got round to installing my Appradio 2, but an fed up with the annoying warning I get every time I turn he ignition on. The "objects show, may be in reverse" message every time I select reverse with the reversing camera fitted is getting on my tits, is there any way, I can disable them?

No.

surely someone can make a cooked firmware with it removed,

what happened to the french/russian windows based one that was floating around?

what are the .hat and .yuk files?

i bet one of the guys on xda forums can open them up and cook something
