No, that's not a 'BM24'. BM24 is the dual-tuner radio made by Becker.
The radio pictured is the C23, single tuner radio. A C23 is the "Business RDS" model, whereas the BM24 is the "Professional RDS" model.
The C23 used to be made by Philips, and was also labelled as a Philips model PH7851. Now that Siemens VDO purchased the Philips automotive nav/stereo systems manufacturing business, the radio is now labelled as made by Siemens VDO.

I tried very hard, and discussed the problem with some very knowledgable and very experienced people who know these systems better than me. The conclusion was that the LRO (Land Rover) nav is coded in the firmware (EEPROM) to read only the LROC01O boot loader. We tried every trick we knew of to try and change the boot loader to BMWC01S, and get it to load the BMW nav software. All to no avail.
I finally solved my problem of what to do with the LRO nav by selling it to a person with a Range Rover who needed the original nav :-)
That has terminated my research into LRO nav units.
