The following may add to your dilemma rather than solving anything but let me toss this out.
BMW "did" make available an LT specific CB add on accessory in several versions. One was for the '04 ('05 in the USA) and later K1200LT's with the Voice II. It was a branded version of a J&M product. The part number for the CB (and associated wiring harness and mount bracket "was" 71600447937. Part number for the associated antenna "was" 65212337380. These are from a two year old accessory catalog.
A non-current version of ETK is not listing the CB. My recollection is that the CB part was a bit under $500 and the antenna about $215 or so. The unit mounted on the left brake reservoir area and had specific connectors for the LT wiring harness. Installation was several hours labor.
I'm not a parts guy and fellows that are whizzes with BMW's parts stuff might get your more, but, Anyway, there used to be stuff to do the CB part of your query. Those part numbers may give a dealer a way to find old stock in a warehouse or something.
As for the GPS....as has been discussed elsewhere here, the mount and wiring harness that came on your bike were specifically for the Navigator III Adapting those bits to newer generation GPSs is sometimes possible, with some creative effort that others here have accomplished.
I've seen post '05 LT's with an integrated Voice II, Nav III, BMW CB and it all worked. That was "then".
