Why is my wifi not connecting

I have installed an android car stereo with OS 4.1 everything else is working well but the wi-fi is refusing to connect,when i press the ON button it moves back to OFF. Model of Head unit is AND 9000. I have tried several times but no luck. I have also tried connecting using 3G and there is no connection.

Is there any wifi signal where the car is? (You won't get wifi in most places.)
