Here's my take on the Range Rover III radio.
L322 antennas are printed on the glass. Key fob, AM and 1 part of the twin FM come from the tailgate window, 2nd FM and old analog TV come from the left side rear window. Both antennas are amplified close to the glass. Both antennas are limited in frequency to the range of 0.5MHz (bottom of AM) to 450MHz (above key fob) while (UK) DAB is around 220MHz (above old analog TV and below the top of digital TV (700MHz). The key fob, analog TV, diversity FMs and AM are mixed just after the amplifiers.
The amplifiers have blocking filters for all signals below 0.4MHz and above 450MHz so you MAY be able to use a simple passive splitter for DAB. If not you will need to find substitue amplifiers that have 3 outputs - digital TV (includes key fob frequencies), DAB and AM/FM. Don't despare though, BMW, Mercedes, and a whole lot of other vehicles have the same problem so the demand will be fairly large.
Any techies out there that can confirm this ???
