Compared the CCF of a Range Rover sport that has the same amplifier fitted and adjusted CCF accordingly. Amplifier AUD4, Pemium Sound, Large center speaker etc. but the Amplifier doesn't show on the list of modules, red cross on the AAM on diagnostic page. There is RX TX light in the MOST bus and music is playing.

When I try to add a new amplifier it obviously shows the wrong calibration files. When I proceed it gives an error and says "Communication error". I think I have read that in 2012+ Discovery 4 the Sat Nav display module is the master of the entertainment system. After copying the relevant CCF parameter values the display looks correct with Meridian enabled. From the SAT NAV the communication with the AAM module is via MOST. Not sure what I can do to get the AAM enabled.

it says you're working offline, at the top

well yes it is a fully working SDD version which can download required files, but in offline mode. Aren't we all using more or less "tweaked" versions of SDD?

i dont see the same message on mine, if its expired then you need to reinstall i believe

I have upgraded several other modules, I honestly don't think this is causing the problem that the AAM module is not discovered.

That is not the issue here. Shows offline but CAN download files.

Thanks for the clarification

I entered the VIN of the donor vehicle manually for SDD to start with, and then the AAM, ACM and other entertainment system related modules all got green marks after device discovery. I altered the VIN_MODULE_RECORDSET.XML file of the present vehicle to match the WERS codes for the 2012+ entertainment system, but this did not help. When you manually enter a VIN in SDD to start a diagnostic session SDD uploads a ZIP file from the /ProgramData/JLR/..../XML/AsBuilt directory and unpacks the file for that specific VIN, which contains 2 files, the VIN.VBF and VIN.XML file. Then SDD creates several files based on the information from these 2 files. The VIN.VBF file holds basically CCF information, which can be altered with a CCF Editor to match your configuration, and the XML file holds module information. While the 2011 ACM hangs on the Medium Speed CAN bus and MOST bus, the 2012+ ACM is MOST only. Letting SDD read the VIN automatically causes problems, as it expects for example the ACM module on the MS_CAN, but it will not find it there. The AAM in both cases is MOST only. It must be possible to alter a file to make SDD believe it is looking at the later entertainment system to begin with. You can unpack the correct AsBuilt ZIP file, alter the .vbf and .xml files to your likings, then make these files Read-Only before repacking them back in the ZIP file. When you then do a search for your VIN and delete previously created files under /LandRover/Sessions and other directories, to remove old information, and enter your VIN manually in SDD it will upload the ZIP file, unpack the .vbf and .xml files that you altered and start the diagnostic session based on those parameters. This thread helped me into the right direction:

Hm yes the vin cannot be written on a used BCM so needs virginising see pelican diagnostics
