I just recently updated my f700bt to 2.8 and before i updated it, i could watch videos and everything just fine while driving but after i update it, i get a warning and i cant watch it anymore while driving.. what do i do?

Did you have your unit modded at all? It sounds like you erased your former softmod. You probably can't enter location via gps anymore while in drive either.

yup, sounds like you over wrote you software mod, looks like its time to either redo it or just do a hardware bypass.

so easy a caveman could do it!
