Umberto,

Over the last couple of days, I started to get an error on the Nav screen - MAP DVD error...this started to occur with more and more frequency, but would clear by itself after a minute or two after which I could use the Nav system again.

Then, last night, after giving the MAP DVD error, it changed to a new error message: Navigation System not available for an hour, after turning the car off the DVD screen remained stuck on the logo almost all night long. This morning, started the car and the NAV screen is just blank, doesn't respond at all, nothing.

I replaced fuse 53 this morning, and briefly the nav screen started up again to the LR logo...and then after a few seconds, dies again.

Before I tear out the DVD player itself, have you got any thoughts on other items to check?

Thanks
Paul

Have you already tried cleaning the disc in the drive from dust? If you have kept the older version of the map disc, try popping it in the drive and see what happens. Move the driver seat all the way forward and check connections on the back of the DVD player to make sure they are all securely fastened. Perform a hard battery reset. There is only so much you can try with this stupid MOST system... If the problem remains, chafing on some of the fiber optic cables under a seat may be causing the fault, in which case I am afraid a dealer visit is required... There was a TSB a while ago about that, I'll dig it out if you need it.

Yes tried all my nav discs already. What concerns me is that entire screen won't come on at all. Not even the 4x4 screen or the settings, just a black screen. Maybe i need to do a hard reset by disconnecting the battery. Not sure why the DVD player would cause the entire system to shut off.

The nav is part of the MOST ring, so a malfunction could affect the whole system.

Issue
Customer complains of a fault with the infotainment system.

Cause
There is a known issue where during the manufacturing process the infotainment harness which is separate to the main body harness has been incorrectly routed and can drift into the area of the right hand front seat fixing points, see attached photos.

Secondary causes to check are that the infotainment connectors under the centre console have not been latched correctly or if the issue is specific to the rear screen entertainment circuit check for correct routing, chaffing of the harness in the seat.

This can affect any of the electrical infotainment circuits i.e. navigation, phone, amplifier, radio. The type of fault that can occur can be variable and can happen at any mileage.

Examples of faults already reported are
- Previous destination on navigation inoperative
- Time of arrival on navigation inoperative
- Microphone inoperative or echo during use
- Phone not working but o.k. when used via Bluetooth
- Navigation screen displays "navigation not fitted"
- One or both rear headrest screens inoperative.
Please note these are only a small number of examples and are not a concise list.

Action
If a fault is reported with the infotainment system it is advised that the infotainment harness in the seat fixing area is checked first for signs of pinching/damage and then the connectors under centre console are checked for correct latching or seat harness routing is checked if the fault is specific to rear seat entertainment.

If it is possible to carry out a local repair i.e. a small number of wires are damaged then this should be done using the harness repair kit. If the damage is to co-axial or MOST leads, repairs should not be carried out and that specific harness will need to be replaced.

Note:
Overlays are available but they are not currently listed correctly in Microcat, this is being rectified.
Attached is the list of overlays that can be ordered. Please note that there are no differences between LHD and RHD as the longest lead is the only one available. Any surplus lead should be stored in a suitable place i.e. under the carpet. Improvements to the routing and clipping of the infotainment harness have been introduced, however the issue will not be resolved completely until 09.5my, January 2009.

Spent another hour on this...found out that when disconnecting the DVD player below, the Nav screen comes back on just fine, and the 4x4 and Settings options work perfectly.

I'll check the center console to see if anything is loose there...otherwise sounds like I need to get a new DVD player - believe that might be covered under my extended warranty, so will check on Monday.

Umberto...thanks for the documents...very helpful.

hey umbertob,

my problem is two of my headrest monitors do not seem to be operating at all, should i be checking under the drivers seat which is the left seat on my car or the right passenger seat for the pinched wires under the chair? should i be expecting the wire to be visible? or do i have to take the whole chair off?

thanks.

Joey;

I found this document in TOPix, unfortunately it has no images any longer. So here's just the text of the bulletin.

This should help, and yes you'll have to remove the driver seat and lift the carpet, look around the seat track.

[joeynahlous]

okay rafa that will do thanks, but im still confused on which seat it is the drivers side or the passenger cause i think they are talking about a right hand drive vehicle!i dont wanna be taking the wrong seat off and realize it was the other ! :lol:

 

[rafa]

Hey joey;

In my car it was the driver side, so the left front seat.

Rafa

 

[joeynahlous]

okay man, im going to give it a try this weekend and see were i get, hopefully ill find something, if i do ill make sure i take pictures and post them.

thanks alot!

 

[rafa]

So Joey;

The harness runs to the right of the seat, between the seat and the console.
Once you remove the seat look at the right track and you'll find the harness.
It's supposed to be to the right of the track (may have to remove this track only, the harness is nowhere near the left track). So make sure you reposition it as such, otherwise the seat mechanism will chafe it again.


Rafa

 

[joeynahlous]

okay so is this all happening under the carpet or ? and once i take off the right track i slide the harness to the center of the seat so its in between the left and right track? will the wires be damaged? what am i looking for exactly?what should i expect ? did you tackle this issue or did the warranty at the dealership take care of it? is there a page that gives the instructions on removing the driver seat? i found one which was for the passengers side, will it be the same ?cause there are alot of wires attached to the seat itself.

 

[rafa]

Joey,

Finally found the old tread viewtopic.php?f=5&t=28894&p=222083&hilit=rear+entertainment+harness#p222083

 

[joeynahlous]

thanks rafa,

i will work on it this up coming weekend, i was wondering if you worked on it personally or the dealership took care of it, do you know if all this work is done under the carpet? do you know any forum about how to take off the driver seat?

thanks for your help

2006-2009 front seat removal / installation (from the workshop manual, which always makes it look and sound easier than it is...):

 

[joeynahlous]

hehehe thanks umbertob, it surely does make it look easier, i took a slight look under the seat and thers a whole bunch of wires electrical stuff connected to the seat i dont know how easy this is going to be, 8~ :lol:

 

[bradster]

Having this issue on my new (to me) 2008 RRS SC LE. The left screen is displaying a white screen. ANyone know what type of coaxial cable is used? Would like to avoid buying a harness from the dealer. TIA.

 

[RoverGuy7]

It's not a coax. It is similar to a S-video, but not quite. The term LR uses is IS-bus. Which I believe is Alpine branded. But it is not just a video feed, as it has bi-directional data transmission.

 

[bradster]

Thanks RoverGuy7! Much appreciated.
