Can anyone confirm that the SAT module part number that is displayed in VAGCOM does or does not have the letter suffix (A,D,F, etc.)?

For all I know, the part number displayed in the software is the base number without a series modifier. I would like to upgrade to an rns-e, but I don't know if my Sirius module will need to be replaced.

Alternatively, maybe someone can confirm that a sat module that works with Symphony2 module will not work with rns-e (as opposed to the rns-e versions being backward compatible).

Thanks.
