The W447 Original Equipment Manufacturer DAB Upgrade

Hello everyone,

I know it is possible to add DAB to certain vehicles with the right module, an antenna, and some code, but my 2016 v250d does not have it.

After some research, I've settled on the part number A222 900 89 11 as the relevant module; getting one shouldn't be too difficult. However, I need to check that the fibre loop and harness are there before proceeding, so now I have some questions...

Is there a general location that everyone is familiar with for the module?
Is anyone familiar with this process?

Before anyone mentions it, I'd rather try this option as switching screens is a last choice.

I appreciate it in advance

On C-class estates, it's under the boot floor; on V250ds, I'm not so sure. Immediately adjacent to a fuse box.

I can locate location information for almost every model except the V Class, but the fact that my vehicle does not have a boot floor is frustrating.

I appreciate the feedback, though.

Tell me the number of fuse boxes you have. Go around them and start looking?
