Hi chaps.

I had some work done to replace the fuel pressure regulator and the mech disconnected the battery. Now when I put my key card in, the centre console does not light up or show the sat nav (or radio info). The radio etc works fine but the screen is pitch black.

Any ideas as to how to get this back please.

Many thanks
Chris

Forgot to mention it's the Carminat factory fitted Sat Nav.

Seeing as answers are slow in coming I had a 'play' with it and imagined that when I turned the ignition on the screen had come on...... I then hit the accept button that would send the screen to 'guidance, map etc etc options' I scrolled one down (from memory it is 'map') and hit accept button again and all the unit lights flashed on the sat nav but that's it, nothing on the main screen.

Maybe it was trying to load, maybe not. Fuses are OK too by the way.

Is the mysterious and lonely fuse behind the ashtray okay too? I'm guessing you've already checked it, but thought I'd mention it on the offchance. I don't think the stereo works if that one blows anyway, but it's still worth a try if you haven't already checked it.

On top of that, I believe the Initiale has some fuses and relays hidden behind the glovebox liner. I'm betting you haven't checked those. I think they're for the heated/motorised seats, but the sat-nav screen might just have a fuse in there too.

Beyond that, how long has it been 'broken' for? Is it just today? The sat-nav screen on my 2.0 IDE used to refuse to come on for no reason every now and again, and the only fix was to leave the car parked up for at least a couple of hours and then try again. Maybe yours has thrown a similar wobbler. It might just be okay in the morning.

 

[Cybermanc]

Cheers for that Horatio

The ashtray fuse was OK but I will check the glove box ones tonight when the missus gets home.

It has only been 'broken' since I picked it up yesterday evening so hopefully it will have come back up during the missus' 30min drive to work.

As the battery was disconnected I'm fairly convinced it has something to do with that but bringing it back has me stumped, the handbooks advice is 'blank screen??? Try turning the ignition on':steam: :steam: like I wouldn't have thought of that lol.

UPDATE:

Still buggered and I couldn't find fuses in the glove box and the liner seems well fixed in:crazy:

I checked the fuses in the engine compartment and there was a 20AMP one blown but I replaced it and nothing happened and not sure what it does as the handbook states not to mess about with them??

So....... what the hecky thump is up with my Nav:steam: :crazy:

 

[Horatio]

The glove box liner has a T20 Torx screw right at the back, and four clips around the edge. You can just about see two of the clips as a square U-shaped cut-out, and prizing gently with a small flat blade screwdriver may be needed to free them off. The other two just pull out.

There's supposedly a fuse and relay box in there somewhere, though I haven't seen it. This will also give you good access to the sat-nav CD reader (4 more T20 screws and you'll need a fairly stubby driver if you want to remove the reader.) There might just be a fuse in the back of that.

 

[Cybermanc]

Before I got this post I managed to wangle it out Horatio:d There were indeed a few fuses but all were sound:crazy: The reader whirs into action when a disc is inserted but the screen remains dead. (bummer too coz when I took the ashtray fuse out it needed me to code the radio which I had to do with no readout.... but I managed).

I removed the screen unit from the top of the dash and had a look at the connections there but the plug was in nice and firm.

 

[Cybermanc]

Anyone got any more ideas please?? I even took the headunit out (coathangers are ace lol) to see if there was a fuse in the back of it...... there wasn't:crazy:

 

[markbaxter]

same problem now fixed

Hi if you search for my name you will see I had similar problems . This was eventually found to be the Satnav computer ( the CD drive in the glove box). Cost to repair £ 700 plus £ 80 for fault finding. Dont you just love Renault

 

[Cybermanc]

Will search now Mark.

The temp and the Radio don't show either so would they be buggered just because Sat Nav comp is out? Hope not for my sake

The drive whirs and clicks in ( I can hear it). Will get it looked at though.

 

[markbaxter]

fraid so

Yes I have been down this route you either pay the £800 or purchase a different radio and loose the display. I agonised for 3 months before biting the bullet. I had mine fixed last week. even then they said I required a new gps antenna £ 220 fitted, I managed however to get one from e bay for £12.50 and fit it myself. You have my sympathy.

 

[chris m]

just a thought, have you tried the display bulbs?

 

[Cybermanc]

The display bulbs Chris?

I have had the Sat Nav screen out by removing the large top mounted dome shamed console. I opened the unit and got to the circuit board but the screws that would let me into the back of the LCD screen were too small and looked like a specialist type bit was needed.

Mark, the radio works fine apart from the fact I can't see the channels/time/temp etc. I have seen a Sat Nav head unit on Ebay and am thinking of getting it and trying to pop it in the dash to see if that works.

 

[Cybermanc]

Well I'm no nearer a solution and I have no intention of Renault pulling my pants down so if no-one can help me with a fix................. does anyone know if reconditioned units are available anywhere??

Radio still fine, fuses all fine but screen doesn't illuminate but I'm sure it's the headunit that is causing it not a blown screen.

Carminat Sat Nav blank screen

Hi. I have suffered exactly the same problem as you after disconnecting the battery to recharge it and then reconnecting it. The screen is black which means I can't reset the radio security code. The Sat Nav CD player is whirring away so there is power to that. I have checked all the likely fuses. Did you resolve your problem. If so, how? Cheers

Carminat Sat Nav black screen after recharging battery

Hi guys, thought I'd share my experiences of the above in the hope that it might save anyone having similar problems a lot of frustration and hopefully a lot of money. My car is a 52 plate 2.2 DCI Initiale Sports Tourer and the Sat Nav gave up the ghost about two months ago after I had to recharge a flat battery. Firstly, I checked ALL the fuses and relays in the car, especially the one behind the ashtray, but all were OK. There have been suggestions on the forums about checking the fuses and relays which are located behind the glove box liner, above the Sat Nav CD reader but these are nothing to do with the Sat Nav system so you don't need to waste your time. I had the car diagnosed at a Renault specialist, though not a main dealer due to their ridiculous charges. The diagnostics pointed to the Sat Nav screen as all the other units seemed to be OK. I was able to get a screen from e-bay for under £60 (£1100 from Renault!!) but unfortunately, this did not cure the problem. There is no guarantee that anything from e-bay will work, of course, but the guy seemed genuine. I then bought another from e-bay and that didn't work either. Any of you who replace any of the units on the Sat Nav system need to initialise the system once the replacement item has been fitted. To do this, turn on the radio first, then press the M and C buttons on the CCU simultaneously, then switch on the ignition whilst the two buttons are depressed. If you don't turn on the radio first, the satellite controls behind the steering wheel will not work. I next bought a CCU from e-bay and fitted that. Still no good. So recently, a complete Sat Nav system from a 53 Laguna came up on e-bay so I bought that and started by replacing the CD reader in the glove box and b****r me, the system fired up as soon as I initialised it and I was a very happy bunny. The strange thing is, the red light on the old CD reader was working and I could hear the CD drive whirring away, so assumed it was OK - not so!! I refitted both screens I had bought, just to test them, and they both worked with the replacement CD reader. I was determined that the fault was not going to beat me as the Sat Nav was one of the reasons I bought the car in the first place. I love the car but as other owners will only be too well aware, the electrics can be a challenge! Hope you find this useful.

 

[Cybermanc]

Cheers Chris, will give that a go

Did your ORIGINAL screen also still work then??

 

[Chris Browne]

Hi there. Yes, the original screen worked fine once I had replaced the CD reader. I had bought two more screens from E-Bay and they both worked too so they are being quickly relisted to get some money back!

 

[ide man]

easy repair

Hi
Very good thread ;;; This is why I like this forum I feel you will have saved Renault owner allot of time if it works on other members cars .
As for your old cd reader what is wrong with it as I used to work in the electronics game and I bet it will be an easy fix ;;; to sort your old one out .

 

[Chris Browne]

Hi, I thought I would try reconnecting the original CD reader just to try it and the system came on. I am not sufficiently savvy in electronics to know if a device can be affected by what must have been a power surge when I reconnected the battery and then somehow correct itself. Perhaps what I have done. without realising it, is to reboot the CD reader by taking it out and then reconnecting it. It really frustrates me that there seems to be a culture within dealerships to simply throw customers money at problems rather than trying to find out what the problem is. I suppose their argument would be that it is too expensive to have a technician (whatever happened to mechanics!) spend a couple of hours trying to sort out a problem when he can plug in a new unit in minutes. If Renault had been allowed to sort out my car, based on the diagnostics, I am sure they would have started with the most expensive unit (the screen at £1100) which in my case would not have solved the problem and then worked through the entire system. At Renaults prices, I think I could well have been looking at a bill for £2000 plus. The moral to the story is don't be frightened to have a go yourself and persevere. It is only a machine when all said and done and with due respect to Renault technicians, they are not geniuses.
