On my 2003 Nissan Teana it has an aux ability but I'm unsure if I have to connect something up or if there is a port to plug a 3.5mm into it? Anyone can help me out?

Apparently what you need for your vehicle is an adapter to allow an external source to play through your auxiliary input. This adapter plugs into the cd changer input on the back of your head unit. They can be purchased online.

Please help me too, I just purchased a 2006 Nissan Teana thinking it had an AUX connection, sadly it doesn't so sighlent road trips it is :( Please tell me how I can set up the AUX and where to buy the parts? I am from Auckland, New Zealand

Even better would be finding someone to install it without it costing a fortune

I'm with you Zoe, I just bought a teana too and I can't find where aux goes. Please let me know when you find someone. I'm in Auckland too

Just purchased a GPS with Bluetooth that also has a fm transmitter to play the music from your phone thru the car speakers, it's the cheapest easiest way. Check out ww.prosattechnology.com Or trademe, the GPS I got that does everything including reverse camera too it's a Marbella MK47 7" They have other ones that will do everything too :) Not much installation required this way which is a bonus

Not sure who's watching this thread... Just purchased an MP3/Aux interface and will be installing next weekend. Wish me luck. Warren @ AKL NZ

How did you go Warren? :)

Buy a tech.inc wireless fm transmitter from the wherehouse. $39. Plug it in to your lighter socket and tune yr car radio to an unused station number, then push the nob with the phone symbol on it on the transmutter until it comes up with radio station nbrs. Turn the nob until it matches yr car radio station nbrs then connect your bluetooth from yr phone to it and you are good to go.
