I have a CMU200 and I'm trying to get the K14 (Stereo FM) option working. Now here is the interesting thing. There is nothing in the SWOPT.DAT file. Loads of options are enabled by default, related to mobile phone testing. There are a few that are not enabled, and K14 is nowhere to seen.
I can use the key generator to generate keys, which are accepted, get written into the SWOPT.DAT file, but does not enable the option. Even if I edit the file, the option will not appear. I don't care about the various cell phone testing options, but I'd really like to get the stereo fm modulation working. Is it possible that some units have hard-code options and SWOPT.DAT is ignored? It is a 1100.0008.10 unit, if that matters.
