Retro instal BNS 4 to an A4 B5

[matt1976]

Hi, Just wondering if anyone has any ideas.

I have an A4 advent 2001 B5 with a signal din concert radio. I'm trying to instal a BNS 4.2 satnav. I'm having trouble getting the DSI to recognise the satnav. I've recoded everything using VCDS-Lite (tried lots of combos). I've checked all the wiring against the Instal diagram that I downloaded, unfortunately its all in german but I'm sure its all okay.

The faults I'm getting in VCDS are:

Address 17: Instruments Labels: 8D0-920-xxx-17.LBL

Controller: 8D0 920 980 K

Component: B5-KOMBIINSTR. VDO D12

Address 37: Navigation Labels: Redir Fail!

Controller: 4B0 919 887 E

VCID: 351D542F1C4F

1 Fault Found:

01317 - Control Module in Instrument Cluster (J285)

49-00 - No Communications

I'm guessing this means that I had a problem with the CAN bus somewhere. I've spent hours trolling Google and other audi forums with no luck. If anyone has any thoughts let me know.

Thanks.
