3 Series (E46) built-in Sat Navs - Gassing Station - PistonHeads

PistonHeadsJun 9, 2010 - I don't know much about the OEM sat navs, other than that they cost no less than ... would need to be re-positioned and CD player becomes redundant. ... on forums, they do the job, just about and sometimes not too well at all.

What year/model is a 52 Plate Rangie? That description is meaningless outside the UK.

Has the sat nav got power ? or is there no power to it, do any of the buttons work etc? It might just need resetting if so get back to me and I can tell you the details, please clarify?

I know this is an old thread, but my 2006 325i Nav screen went bank also, but the radio still played. I noticed the glove box light and trunk light did not turn on also. I was told from mechanics is was probably a CID module for $2200, even though I mentioned the glove box and trunk light light were out and specifically inquired about a fuse. The mechanics never checked the fuses, because I checked my fuses in the glove box and found the fuse 61 marked with a BMW symbol that looks like light bulb was blown. The Nav screen started back up once the fuse was changed.

Hi I had a similar fault on my x5 the bmw garage reprogrammed the sat-nav and it has worked perfect ever since, I think it cost about £90 but I cannot remember was a while ago. I certainly wouldnt pay £1450 sounds like there taking the micky!

Hope this helps

dignostic at your dealer is the only way to repair this defect.

Hello There.

My guess would be that your sat nav was retro fitted, i'e not factory fitted. Who ever fitted it didn't use the correct wiring harness. It seems they may have used a wiring harness which didn't have the connection for a CD changer.

If you want to get this fixed you will need to replace the wiring harness which means stripping out the entire interior of your car, i.e seats, carpet, door panel. or you can live with the single CD which works.

If my answer has solved your problem, please rate me on fixya.

Thank you

Hi kuldipdhanja this sounds like it could be an internal fault with the video module or the sat nav drive, you could try discontecting the battery negative lead for 15 minutes to reset the control units, you will have to remove the spare wheel and unfasten the air compressor bracket to get to the battery, this fix may only be temporary but it is alot cheaper than replacing parts. regards mark.

If all other text in the display is in English then you may well have the German language CD... nip to yr local dealer and ask them to check the CD serial or model number against there database.

Hello There

Yes it is possible to install the factory sat nav in you X5, but apart from the head unit you will also need:

1. new wiring loom
2. dvd navigation unit installed at the back
3. TMC radio unit again at the back
4. bluetooth unit

All the interior needs to come out i.e seats, floor carpets, door trims.

If you feel brave enough then there are BMW forums which gives you very detailed information on how to to it, but don't expect to get it done in a day or even two, a week is probably realistic time. It took me 2 weeks to do my first 3 series.

Hope this helps. Please don't forget to rate me.

Many Thanks
