I found an awesome tutorial on the Trip computer/Spedo with message center retrofit, but how about the Homelink overhead console? Can that be installed and programmed as easily as the Trip & Spedo units? Should they be all installed together? Thanks

I don't think so. I gave up on trying to retrofit that overhead console in my car. I am usually pretty patient and crafty with mods, but I think there is a different harness needed in this case.
