Updates on the Sat Nav Discs

[tarks63]

Was there ever a conclusion as to what DVD to use to improve the Sat Nav on pre 2009 DB9`s.
I saw mentioned the Volvo DVD part number ending in 31326246 as being an upgrade on the DVD part number ending in 31310191 Was this the case?
Appreciate any advice as looking to upgrade the disc on my 2008 car.

2012.1 disk set RTI (MMM/P2001) is currently Volvo part no 31357734 (NavTeq part number T1000-19225). This replaced 31326246.
