Getting rx8 GPS / TV working in New Zealand
 

Just wondering if anyone might know about this.
got my rx8 a couple weeks ago, it came with dvd based navigation system and monitor. I understand that i wont be able to use it for playing dvd movie(unless installing the video switcher,i.e from navelectronic).
My question is, how can I get my GPS working in Auckland, New Zealand.
Also the tv tuner does not seems to work fine, it can only get a really bad graphic when trying to watch local tvs
any suggestion anyone?
Thanks heaps in advance..
