XM/Sirius and RNS-E

Ok, it looks like getting XM/Sirius to work requires an upgraded sat receiver:

Sirius for Symphony II/Concert II:
Part No. 8E0 057 593
XM for Symphony II/Concert II:
Part No. 8E0 057 593A
Sirius for RNS-E and/or with tire pressure monitoring system:
Part No. 8E0 057 593D
XM for RNS-E and/or with tire pressure monitoring system:
Part No. 8E0 057 593E

Since audio is possible with the US unit and the older sat receivers, I would guess that the CAN commands have changed to allow more devices (e.g. the TPMS) on the bus.

So, for the US unit ("E" and "R" units), installing the "D" or "E" sat receiver should enable sat radio (maybe you can sell your sat enabled radio together with the receiver :wink: to get funding for the RNS-E upgrade).

The EU unit ("C" and "P" units) does not even see the sat receiver and has no option to select either XM or Sirius. So if you want to use sat radio, don't choose the EU unit.

EDIT: Loading the US software on a Euro RNS-E will allow the use of a second generation SAT receiver even with a Euro RNS-E. See quick links for details about how to load the US software on a Euro RNS-E.
