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.
