Well, I tried the burned nav disc that Mr Simpson kindly sent me........very nice people on here eh

Unfortunately, it didn't work

Just got the same 'Check navigation DVD' message on the screen.



Put the old DVD back in and everything's fine again.

One thing I noticed, on a VCDS scan, it's the only module that doesn't have a coding. Not sure what that means?

Address 37: Navigation Labels: 4E0-910-88x-37.lbl
Part No SW: 4E0 910 887 D HW: 4E0 919 887 C
Component: MNS ECE H43 0550
Revision: 00000000 Serial number: 353EJ047522731
Shop #: WSC 02313 785 00200
VCID: 2E05097BDC17BBEBD1E-807A

No fault code found.

Out of interest, here's the nav player unit details:



What to do next I wonder.

I wonder if an Audi dealer DVD will work?

And how much are they anyway?

Thank you again Mr Simpson, at least you tried.

No worries Echo, it was worth a try for the sake of a DVD.

Original discs are pressed not burned and so have more pronounced dips and peaks so even old lasers can pick them up. Sometimes it helps when burning at slower speed as more time is spent for each bit and some drives or media can produce better results.

Interesting and good to know, thanks.

I still don't understand why the software/firmware update to 5570 didn't include the nav player.

Or is that a separate thing altogether.

In other words, does a new updated map DVD have it's own software to update the nav player?

Does that even make sense? :Confused

Yes, that is exactly what happens.

Also the Nav unit uses Adaptation Channels to set its parameters, rather than using a coding value like other modules. Hence no coding.

You can do a DVD read test by using Channel 065 and value 2 for short test, value 1 for a long test.

Riiiight, thanks Matty.

So the 5570 update was correct in omitting the nav player then?

And, does that mean unofficial discs sometimes don't work because they are burned (instead of pressed), and don't get the proper info for the nav player to recognise it, as Ainarsemms mentioned?

What does a 'read test' do?

Sorry, with technical stuff like this, you have to explain it to me in dummy language

Burned discs will contain the same info it's just that old weak(ish) lasers cannot read them reliably.

I might not be 100% corect but original discs are pressed with template to create dips and peaks, then covered with relective layer. When you burn recordable or rewritable discs they are already coated and you create dips and peaks afterwards.

Ok, thank you for that, I think I understand...........I think

So, even though it can still read the old original DVD, the nav player is getting a bit iffy.

Does the DVD in the nav player spin continuously when the ignition is turned on? Or does it only start spinning when you select the nav button on the MMI? If it's continuously, no wonder it's getting a bit narky in it's old age!

It seems the only option is to try a genuine dealer DVD, or change the nav player for a newer one.

I'll report back if/when I get it sorted.

Many thanks for everyone's help.

This seller reckons his are genuine. Even though he states no returns, if it doesn't work eBay will refund you
