Hi, a string of questions that I hope some kind, knowledgeable person has the answers for.

I recently acquired an B5 2.8Q A4 Avant with an RNS3.x factory-fitted system including the TV option. It's a very cool bit of kit and sounds exceptionally good. It came with Yr 2000 map software and I would like to update it. I believe the last version produced for my non-DX unit (9/ 99) is 2007, but I can't determine if it includes postcode support. Can anyone confirm that?

Can anyone help me to get hold of this software, and what would the likely price be? I read that there can be problems with the included firmware update if you skip intermediate updates (e.g. 04/05). Is this true or can I just pop the CD in and it will work OK?.

Also, I was thinking whether it is possible to upgrade it to receive digital TV, however it looks as if it would be expensive. Kufatec seem to be the only source with a fully functional kit, but I'm not quite sure if there kit works with RNS3.x (<11/99) or only with RNS4.x (>11/99 but looks identical).

Also, how can you know if the system is Bose or not? Mine has the sub behind the LH trim in the cargo area. Does that mean it is the Bose setup?

Thanks for any help.
