k thank you i was worried i messed some thing up in navtweak but glad to know... i think it has to do with the navigation system stayin on. if you notice when u turn off the car(or atleast in my zed) u can hear is still running and if u turn the car off then wait a minute and turn it back on the warning screen wont even appear.. and it'll still be on the same screen as when u turned the car off i.e. menu/gps/ what ever. just a thought...
