I struggle to find new reliable lasers for them. So I'm reluctant to pay out £30 on the offchance it would work.

I'd recommend buying a known good NCDC or NCDR, and swap over the CD mechanism. That's what I do now.

Sure, although swapping CD mech over is trivial, honest :)

Thanks

It might be within my ability I will have a read up if there is a guide and see if I feel able.

Just to confirm Iím looking for either a NCDC or NCDR head unit from any Vauxhall assuming they all have nav fitted .Then take apart and replace the entire mechanism which will have the laser and itís workings all fitted so like for like swap.No coding or anything else involved ??

Thanks TB

Yes, you swap the top CD mechanism over, plug and play.  From memory, 2 screws hold mech in, and there are 2 fiddly (but not hard - just take your time) ribbons.

Coding is held on the forward board of the NCDC/NCDR, which you won't be touching, so you should have no coding/pairing issues.

Well spent a wet afternoon dismantling and re-assembling a NCDC 2013 and its mate.

Bought what I hoped was a working NCDC 2013.Took it apart and removed the nav mechanism complete and then removed the same from that in my car and swopped the 2 and re assembled.

Had high hopes and with fingers crossed refitted head unit and all worked ...except the nav part..same fault as before disc just gets drawn in and after about 30 seconds disc gets spat back out and unit askes me to insert disc.

Have done this around 10 times each with the same result so conclusion is :

1)..Either original diagnosis from Gerners was correct and something un repairable is the fault. :-[
2)..Lightning has struck twice and headunit I bought for £30 has the same fault as mine. >:(

Think Im now chasing a lost cause ,unless anybody has any pearls of wisdom.

On an aside the removal and refit was quite straightforward ,except the very fiddly little clips that hold the 2 ribbon cables into their sockets ..Very brittle and bits broke almost just looking at it but all replaced so did at least prove to my self I could do it

Use the CDC lens in the nav unit :y

Assuming it works*...

*5 pints into a Bank Holiday Sunday I can't see why it wouldn't, but whilst you're there...

My skill set doesn't extend to the "full" laser replacement ,hence why I was keen when TB advised removing the mech from another headunit and doing a straight plug,n,play.

Seems there is either a fault within the main unit or I have been very very unlucky and had :

A) ..a specialist laser replacement company not want to replace the nav laser and give me a full refund..seems odd  or

B)..bought a 2nd hand 2013 with a fault to the laser also.

Enjoy your drink

Option (A) didn't cost me anything as was given full refund for 2 sets of postage to  Germany so couldn't see what they gained from that especially if they could replace laser.

Are Nav and CD laser units the same then ?

Still don't fancy getting into fiddly springs and connections doing a full swop to find fault remains

Did you use the original ribbons, or the ones that came with the replacement?

Ribbons that were attached to the mech from donor .
Would that be the cause then ?

Have you tried a different disc ? My original GM disc does what you describe, but the newer copy I have works fine, although I don't use it as it will likely knacker the laser.
