I submitted a request on their site for more info for my 04 LX. Here's the response I got:
Thanks for your inquiry.
I am sorry to tell this unit can not work with some protocols of LX47O. So we stopped selling it for LX470. Sorry for inconvenience.
If anything we can do, just feel free to contact us. We are ready here.
Best Regards
Andy
huh, maybe thats why I had some issues. I am guessing it likely has something to do with that awful ML stereo system.
