Sat nav drive laser cleaning

[Stefan Wilczak]

Has anyone used a DVD cleaning disc in their say nav drive? I am getting an intermittent problem with it not recognising the DVD. All was fine until I removed it for some stupid reason and I am wondering if a clean might be a good idea?

Try gently wiping the DVD with a lint-fee soft cloth and reinsert it. That often does the trick.

Regards,

Clive

Good suggestion but no luck! It is now no longer intermittent and it does not seem to be able to load/identify the DVD? Everything else works fine so I guess it is the drive in the boot that needs a fettle. Has anyone any experience of http://www.mapleaudio.co.uk in Bath - they seem to repair these things?

I just had same issue on my BMW X5. Apparently the Gel around the head dries out and causes a read error as it can't align properly. My BMW is around 6 years old, so this looks like the lifespan on av. miles car. I sourced and replaced the drive myself - via instructions on you tube on how to take out of dash and stick the new module in.

You may find similar instructions for PCM - I quickly found this video, which takes the module out of the dash

This listing on ebay is for the a DVD drive for Porsche and is like the one in my BMW. Its a simple module to change.

Although the cheapest and efficient company I found for the DVD drives was www.navigatie-onderdelen.nl

If the part number in this ebay listing photo is correct for PCM you have, CDM M6 4.5/52, then look at this link below where they are Euro 77

Its quite straight forward just a few torx screws and ribbon cables.

Hope this helps if this is the issue.

Cleaning did not work for me.

The alternative is a repair from Porsche ££££££ or a sat nav repair company who look for around £250 to supply and change the DVD out.

Clive - really good post thank you. You have given me a direction to go in and I will have a surf around and see if I can get a unit for the DVD drive in my 2005 C2S. The unit is actually in the boot above the CD auto changer - hopefully I have managed to upload a photo of it.

I think I still need to have a go with a DVD cleaner before I go unscrewing things - was the one you tried just an off the shelf type?

Fingers crossed this seems to have been solved by Swindon OPC where the car has just been for a bit of work today. They 'reset' the sat nav and it seems to be working now - yes I am holding my breath! It was interested to know from them that if these units go wrong they do sometimes send them to 'a place in Bath' for repair - depending on the fault - I suspect it is Maple Audio (http://www.mapleaudio.co.uk) so that might be useful to know. Also, in my Googling around for people who repair these things I can across Revtronic who have a pretty good and informative website - http://revtronic.com/?portfolio=porsche-997-navigation-repair-pcm-1.

Hope this helps if you end up with a similar or more catastrophic problem.
