Evening,
Apologies for the delayed, been a busy evening here.
Now Im really confused regards which RNS-E you have.
This from your scan:
The part number (4B0 035 192 T), component name (RNS-E HIGH EU) and firmware number (0690) point at this being a RNS-E Mk1. The picture in the above post shows its a Mk2.
A Mk2 RNS-E would have a part number ending in 193 (or if from a Seat it might be 3R0 035 192), the component name would be RNS-E PU EU and the firmware iteration would be 270 as you stated in your first post. Is this scan result from a different vehicle or from a time when you have a different RNS-E fitted. Do you know if this particular head unit has had any internal components changed.
Whatever the answer is, the coding that you have shown on the scan result is correct for what you have fitted in your A2. Can you confirm where you got the coding of 321757 from in your first post as this is not present in the scan result.
To get the caller ID displayed on the top line of your DIS you need to amend the figure in Channel 62 of Instruments. Change the stored figure to 7.
From memory this is broken down as: +1 = default setting, +2 = telephone/caller ID and +4 = Nav display in DIS. I'm guessing that your stored figure will be 5 so just add the 2 to it and save it as 7.
The above coding in Post #7 along with the amended figure within instruments should have this fully working.
Hope this helps.
Kind regards,
Tom
