Hm… I was actually thinking of using something like this, in combination with Alpine's "Vehicle Display Interface",
to create some way of accessing the track lists and radio presets of my Alpine HU from the trip computer,
the same way it currently can access that from the Ford OEM HU.
That might require a CAN shield and some more details of both Alpine's VDI, and some breakout testing with the Ford OEM HU.
Came across this thread via Google, and just had to register to drop a note of thanks to FordNoMore. :nw: His Alpine remote codes (back on page one of the thread) enabled me to get the steering wheel controls of my "new" '97 ZJ (Grand Cherokee) working with my stereo. Great stuff. :clap2:
Best regards, Kári.
