There are no integration devices made that will work for us yet, I am bugging all the manufactures but so far none seem interested, part of that is the low volume of cars out there, Ford making little changes to different cars making it a specially item and now announcing the chance to what looks like not compatible with our earlier ST's.......
The best bet so far is to upgrade speakers, add a sub, etc, better yet, add a processor before an amp for the rest of the speakers and sub as well.
I need to follow up and find who to contact at Ford as I want to convince them to unlock the rear view camera in the Body Control Module to at least give us a change to work out the rest of making one work.
