Renault Laguna 3 Carminat Problem

[CitroenCX]

Hi,

The Carminat in my 2010 Laguna is displaying only clock and temp. I’ve reset it several times, and have also updated the SD card. This seemed to work first time but it’s gone back to clock and temp only.

Any idea how I can fix this?

Cheers

Hi
Is the radio working?
Have you tried reinstalling an old backup?
Is your SD visible on Tomtom Home.

Hi, thanks for the response.

No, radio not working. Screen shows only time and temp. I don't have an old backup as I've only had the car a few weeks. SD is visible on TTH and I've updated it. When I did this, then updated the Carminat, it worked and I thought I'd solved it, but it's back to time and temp only now. Gargh.

Would a replacement SD card make any difference?

 

[Willy875]

I don't think it's the SD card that's causing the problem, there must be something else.
You can try with another new SD of 8 GB maximum.

Have you checked the fuses unless there are wires disconnected at the back of the GPS.
Another question when you bought the car did the GPS work?

 

[CitroenCX]

Hi, yes, fuses checked and all ok. Everything worked perfectly when I bought the car; the screen suddenly went to clock and temp only and all sound a couple of weeks ago while driving.

I assume to access the back of the unit to check wiring I’d need to remove the top of the dashboard?

 

[CitroenCX]

OK, so I ejected the SD card and left it out for a few hours. Reinserted it now, started the car and the system is working. How long til the fault returns, though? Who knows? This is no way to live

 

[Willy875]

It must be the contacts of your SD card or GPS that must be dirty, try to clean it delicately with a soft cloth.

 

[CitroenCX]

Will try that

 

[CitroenCX]

OK. Back to this.

Last weekend the system reverted to time and temp only. I tried the disconnect battery route, left it disconnected for an hour, reconnected and the system was back to normal. It’s worked perfectly all this week.

BUT this morning the problem returned. Back to time and temp only.

I tried the battery disconnect route again but that didn’t work this time. I tried removing the fuse and refitting after 30 mins, but no change.

I’ve restored the SD card via TomTom Live, I’ve cleaned the card terminals and the card slot, but nothing works.

I’m gonna disconnect the battery again and leave it overnight. I read somewhere about wiring the battery leads together - is this a thing?

Would an OBD scanner diagnose the issue? Or will I have to take the car to a dealer?

Thanks in advance for any advice.

Instead of disconnecting the battery, have you tried simply resetting the device to factory settings?


Connecting your car to the Renault dealer's case can help detect a GPS malfunction.

 

[CitroenCX]

Thanks again for your response, Willy. I can’t reset to factory settings if the device won’t power up (except to show clock and temp) or can I?

Before I take it to a dealer, would a handheld OBD2 scanner be good enough to detect a malfunction?

 

[CitroenCX]

Well, left the battery disconnected overnight, but that didn’t work. Gargh.

You can also try:
Turn off the engine, then remove the memory card.
Reinsert the memory card, wait 30 seconds, then turn the engine back on.


Then, it may be that your SD is defective.

Maybe you need to buy a new SD and copy all the contents of your backup to the new SD.

I’ve tried the first one many, many times. I have a new SD card so will try that next.

OK, me again. Restoring files to a new SD card on TomTom Live since 0930 this morning. Three hours thus far - is this normal? I have good upload and downloads speeds on my network.

The easiest way to clone a Carminat SD card:

1/ put the blank card in the PC card reader.
2/ go to the computer to find the GPS backup file
3/ select the internal memory tab then copy and paste on the new SD card.
4/ insert the SD card into the Carminat it is recognized as an original Renault card..
5/ put it back in the PC reader the updates are done normally.
----------------------------------------------------------------------------
the 1706 elements are transferred to the SD card.

 

[CitroenCX]

Thanks again, Willy. Tried all of that, still no function. I’ve tried two separate, brand-new SD cards, and also backed up and restored the original Renault SD card. Still time and temp only.

I’m leaving home at 4am tomorrow on a long road trip. The thought of doing it without a radio is horrible.

Anything else I can try?

 

[Willy875]

This is just an idea.
If the temperature and time are displayed, I don't think the screen itself is the cause of the problem, but the harness or the GPS box behind the dashboard may have a problem (a poorly connected plug for example).

So remove the GPS and see if the plugs are properly inserted.

OK. Has to be worth a try. Incredibly, for someone with very little aptitude for this sort of stuff, I gained access to the back of the screen. There is one unconnected plug, but there appears to be nowhere for this to go, so I guess this is correct?
