2G and 3G Shutdown - Software update

[Percy]

Here in Europe the 2G and 3G will soon shutdown and all cars with Sensus need a softwareupdate.
Spoke to my serviceguy at Volvo and he said that as i have retrofitted B&W Audiounit the software update did not work at the last service, he will most probably not be able to make this softwareupdate.
Anyone knows if it is possible to just update one module or if he needs to do the full softwareupdate which stops when a unknown module is detected?

Smilar question - If I want to change the VCM or TEM software to support LTE, will I also need to replace the hardware? I think so. The 2G, 3G VCM modules have different connectors than LTE; it's not a plug-and-play process. Has anyone performed such modifications and would like to share their knowledge?
