NAV system

[Black Beauty]

I purchased my LR3 in South America, it did not come with the NAv system due to some poor reason as to why it would not work. I now understand that the graphics for the 4WD systemare also displayed on this panel. Can the NAV screen be retrofitted by a technician that knows what they are doing?

It is possible. You have to get a few parts and add some wiring.

Thanks Trynian,
I suspect that as I already have the bluetooth and the Harmon Kardon system as someone suggested much of the wiring is in. What I am intrigued about is any possible reason why the GPS system wouldn't work in South America. Basically thats what they told me in the dealership but never really gave me any plausible reason why.

Thanks

It has to do with the satalites the system uses. Very likely they don't have the coverage in South America, If you knew what sats the system uses you could find out the coverage. The system needs a minimum of three at all times for a position fix.

HUH? There is only one GPS satellite system that I was aware of: http://en.wikipedia.org/wiki/Global_Positioning_System#Navigation_signals

No wonder LR went broke - launching all those sats must have cost a small fortune even with a hole over south africa ;-) BTW - the sats dont park over any given site, so if there are holes they move.

I have no idea how many systems there and what coverage is provided by each. It would make sense that there is only one system for world wide but again coverage is determined by the # of sats covering an area and it takes a minimum of three. This is the only logical explanation I can come up with for why it would not work in this area. Of course another would be that the Nav disks do not cover the area (Maps).

My hand held is suppose to work anywhere in the world so who knows. It will tell you where you are but if no detailed maps of the area all you get is your location and coords on the continent or land mass. Since vehicle GPS require routable street data to do any course directing that is probably why they say it doesn't work if no detailed data for your area.

Thanks, I am beginning to get the picture, a friend of mine bought a Garmin recently and downloaded all the South American City Maps with regional centres. all works perfectly fine.
Maybe I have to drill out the local dealership Gonzos

Thanks,

Where you are has nothing to do with it. You can at any time see all the satellites that your on by using diag code 753 and doing the NAV tests. There are 2 type of GPS satellites, military and not military. Both can actually be the same bird but the mil sats are encrypted. And their are hundreds of them in the air. A standard GPS picks up 6-10 birds.
