Definately not.

They run on two system here in Japan. One is a GPS based system that superimposes your position and direction on maps stored on a DVD or HDD.

The second system does the same, but uses terresterial positioning rather than GPS.

Either way, you'll need to get a GPS based system WITH Australian maps in order for it to work. Since each navi system manufacturer has a different format for their maps, that's going to be extremely difficult.

It'd be easier and cheaper just to buy an equivilent system in Australia.

PS On a side note. The boss of a friend in NZ has a navi system in his car that was terresterial based in Japan. It now permenantly displays the last location signal it recieved . . . . . . . . . . . The car thinks it is about 100km out to sea from Tokyo.

I think they're all GPS based these days, though I believe Japan has DGPS (Differential GPS) where additional ground based transmitters transmit a correction signal to further improve the accuracy of the GPS location calculated by the receiver. Some cars have a secondary inertial system to provide location info when the GPS signal isn't available.

But IG has hit the nail on the head regarding the problem, which is map compatibility. Each manufacturer uses a different format, and I'm not aware of any mainstream Japanese manufacturer and/or OEM NAV system supplier who has maps available for Aussie.

Therefore aftermarket for Aussie is the only way to go, something like this:

I reckon there is a business opportunity in Aussie and NZ for someone who can reverse-engineer the various Japanese map systems and produce local maps for them, I've seen heaps of imports recently which have nav systems that are essentially expensive paperweights!

Sat navi is a dead industry in Aust as far as I'm concern...

Obviously not, the new Commodores and Monaros come with them as options and some even factory, hell even Nissan Maximas have them.

Im sure the police think this is a grey area, i have never heard of anyone getting an infrigement related to in car DVD's or Sat nav systems.

...last time for the reading impaired!

Perhaps the Sat Navi was already turned off.

Any installation by an auto electrician has to ensure the TV is off when the vehicle is moving, that's the only requirement FOR AUST! Sat Navi by right should remain ON for it's purpose, however as I've explained above again units overseas especially the Japanese units are not restricted to this STUPID rule...so when POWERING OFF the TV will also POWER OFF the SAT NAVI...i.e. backlight off = nothing can be viewed anyway!

If you could some how inhibit the TV or prove to the officer the TV was not active in the background then you will be OK.

Perhaps Holden, Ford and Nissan have done for the Aust market...certainly wasn't the case in a friend's Aust delivered E430. AFAIK other makers are using the speed signal to trigger and turn off the backlight to comply.

Back on topic, Troy you've got a good point there, I think someone brought it up on PF too... how can you use the Navi in AU when it's off while you're driving?

Voice guidance is the key people..... I've heard of some systems that can be configured to switch the screen off when the car is going above ~5km/h, but the unit still gives you the voice commands - eg 'turn.... left.... in.... 100... meters.....' or my personal favourite: 'Make.... a.... legal... u-turn...' when you manage to confuse it!

The manufacturers who supply Sat nav as an option probably have an exception to the ADR's for allowing the Nav screen to be on.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
