The other question is ; The radio is already rooted, Why i cannot enter to the develop options for activate the usb debugging, usually on all my android devices i go to "Phone information" , and i press for some times to "compilation number" and the develop option get activate, but on these radiocar unit it doesnt activate. Is there any other options for activate it?

Hi Aviv, did you find an answer ?

Everything is working well but due to wifi connexion, after a few minutes the system try to update and freeze.
But without a wifi connexion, i can't use my GPS (throw google map)
Tell me what did you do please.
