Messing about with the Amundsen unit in my 2007 Roomster Scout today when I noticed 3 wired feeding the quadlock that have been intentionally isolated and taped to the loom - have a look at the green, black and yellow wires in the photos.

 

Anyone able to say what these wires for, and whether they may assist in getting navigation in the maxidot?

I can't say for sure in a Roomster, but in other vehicles the maxidot/navigation integration is all done over CAN-bus. These are probably the orange/brown and orange/green wires in your second image.

 

Have you got an autoscan from VCDS?

 

Did you ever follow up this post: http://www.briskoda.net/forums/topic/395292-columbus-rns510-in-2007-roomster-scout/page-2#entry4647754

Canbus system T 1.6 on the Fabia/Roomster, not T 2.0 as in Octavia/Golf etc, so integration between RNS/Maxidot via VCDS alone is not possible as the RNS unit can't be accessed. 

 

The previous thread? I gave Connects2 the pinouts and the 5J canbus module details and asked for a loom, but they didn't understand the question (!) ...  so I gave up on them. 

Are there any cut wires in the pins in the quadlock?

Which pins on the blue connector do the black/gray/brown wires go to?

 

Assuming it's for an aux input somewhere, the green/yellow might be connected to the black for extra shielding.

There is an aux input socket by the handbrake

Then I think you've identified them as the shield/ground for the aux socket  :)

 

As to your nav/maxidot issue, I think you need to install a 5J0035751. Probably easiest to make your own loom from a quadlock extension as the wiring looks simple.

If it were only that simple! I wouldn't have a clue where to start ...

 

A quick scan of the Fabia/Roomster pages shows that this loom would sell well, there are many who would love to fit Amundsen/Columbus units to older cars but want better integration than is available at the moment ...  anyone that CAN make such a loom in UK would certainly cover their costs. 

 

There are canbus adaptors on the German eBay pages but at between a reasonable £57 and totally outrageous Kufatec at £250 (!) however I just don't trust Google Translate enough to take the plunge. 

For the 5J0035751, I would:

- grab something like this: http://www.ebay.co.uk/itm/111956982067

- splice cables into power and ground

- cut the CAN-bus cables and extend if needed

- take those 6 wires and attach to the 5J0035751 as shown on the top of it

 

Completely reversible and I believe should give you the best chance. Might be worth asking your local dealer how much a 5J0035751 is as I've not seen them online.

 

The £60 CAN-bus adaptors probably aren't what you need. Typically they just provide a switched ignition/illumination feed for aftermarket headunits, this is because they aren't included on the quadlock.

 

There is a £200 Kufatec thing https://www.kufatec.co.uk/shop/en/Volkswagen/Touareg-7L/CAN-Bus-Interface-VW-RNS-510/MFD3-CAN-TP-1.6-w/TV-Free2?action_ms=1 but I've no idea if it's suitable for your Roomster.

 

I'd definitely be aiming for the 5J0035751  as it's listed as being correct for a 2007 Roomster here http://www.oemepc.com/tvn_result/search/tvn/5J0035751

 

If you can find one, myself of Eddie-NL might be able to help with a loom.

Thanks for the update.

 

I've heard mixed reports of the Kufatec part on other forums (early Touraeg has canbus 1.6 too), and it's bloody expensive - I share your doubts about the other versions available. 

 

There is a fair bit on the Russian and Polish Skoda forums about the 5J0 part you mention - I'll speak to my dealer and will probably take you up on your offer of a loom as this stuff is way off my reservation.

Just found this on fleabay - would this be a suitable item to modify?

Not sure, its connector doesn't look right in the image.

 

The extra taps make it slightly easier to use but I wouldn't say it's worth more than double the money of the one I posted.

 

Edit:

 

Even cheaper: http://www.ebay.co.uk/itm/262084304076

 

The 5J0 module will be the expensive part ;)
