hi aise.
first,thanks for your answer

you mean that there is no conccetion with nav,
so should i take it out from the back to check?

if your screen has only blue and white colors (normally the background is black) then your nav unit is offline. you can check connections in the back and if that doesn´t help you need to go to your local $tealer to run diagnostic test.
