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.

      Stock rb25det neo questions

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.

      I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.

      @Dose Pipe Sutututu I read your replies RE: R35 GTR MAFs, any ideal spots to put on? Obviously will need the adapter plate. Will be having a cross over intercooler fitted shortly, would putting it a bit before the TB be okay?
