Tried doing a battery off reset, remembering to power down the nav by waiting 1 minute after IGN off [LED goes out after flashing]?

Nope. The Beta version is always the latest.

Brian:
TCU coding for ECE or CDMA model is almost identical
And NavCoder regonises all TCUs correctly - so far...:D

Cool. I will note this.

This takes me back to my possible worst-case scenario for Stringbag... that this TCU may not have BT capability.

Brian, I'm starting to think the same!
Jochen, thanks for your help!
Okay, downloaded the latest (beta) navcoder.
select Code/Telephone
Click on 'Read ID'
Populates the data on top 2 lines, everything else blank.
click on 'Read TCU'
The bluetooth box is Ticked.
Everything else in the bluetoth section is blank.
VR section remains greyed out.
SDV section is active, but blank unless I click on SDV defaults
'code TCU' remains greyed out.
Even if I populate all the blank fields on the page, the 'code TCU' remains blank.

Jochen, how do I get a log of the TCU coding?

Many thanks for all your help everyone!
Stringbag

Tick Tools - Log Ibus Messages to make a log
Then read TCU again

You have coding index 03, which has no VR support.

But I'd like to see a log of your reading your TCU, because name, passkey, SDV settings should work.

Thanks, I'll do it tomorrow morning.

Log file sent.

Well, with a new beta by Jochen (massive thank you) I can now code my TCU.
However, I can't initiate pairing!
It displays 'telephone' on the nav screen, but when I select it, all it says is 'insert card!' or 'emergency'.
Only one of the leds on the nav screen flashes and that is red.
I have tried holding down the R/T button on the steering wheel, the sneezing man and a combination of the two. No change at all.
There is a slot on the TCU but it is far too big for a sim card.
I have an 18 pin connector in the armrest - from WDS it is X4545. I have searched this forum and some have suggested that if the TCU doesn't go into pairing nmode when the ign is first switched on, that you need to press the paining button. I don't have one, but can connect the pins in the X4545 connector.
I have not tried this yet because all the suggestions I have read only have 4 pins going to the armrest x4545 - mine has all 18!
How do I work out which of these pins is the right one? Pin 32 isn't it on the 54pin adaptor in the trunk.
Any ideas?
Thanks.
Oh, and happy Easter!

TCU pairing requires no button presses.

The TCU goes into pairing mode for the first few minutes after ign is switched on.

So:
Put your phone into BT search mode
Then turn on vehicle ign
See what happens

I have head from some people that an eject box may need to be fitted to allow the TCU to go into pairing mode, although this is unconfirmed.

However, no button presses are required for pairing mode.

For some reason Bluetooth is not transmitting. Two phones -a new and an old one can't see any blootooth signal from the car.
The only eject box I have is the old v50 one without a pairing button. Putting it back makes no difference.
All I get when I select telephone on the nav screen is 'emergency' , a phone symbol and the words 'insert card'.
No 'activate phone' or similar.

I'm confused!
