Unbranded unit help

Hi there i bought a 2011 Kia Sportage with a unbranded android 2din head unit.
Specs is as follows:
cortex -A9 Dual Core
DDR3 1GB Ram
Android 4.2.2
MCU Version: 4.3.7-16-61-650101
System version: 2.7.3.8
Firstly i don't know where to get firmware to update the unit.
Secondly i am not sure if it has built in wifi, when i click on the wifi icon nothing happens and when i go into setting and click on for wifi it just says swithcing on and that keeps on showing without anything happening.
Any help would be much appreciated.
