Hey mate, I have this unit and I bought mine from overseas, just so u know if you want to play video on your head unit its not like the other head units where u just wire it to earth, it needs you to have your foot on t he brake and the handbrake up lol.
BUt let me kow if u want details around this, I can link u the part u need to buy, its pretty cheap, I got one, but have not fitted it yet..
Also what price have u got on the GPS unit ? I would be interested if you can find this cheaper with Aussie maps
