Does anyone know off hand what years and models the Harmon Kardon radios off a 09 Ultra will interchange with? I need to change mine out, thought I might look online for a replacement. I have a 09 Ultra. Thanks for any help.
Check Ronnie's HD parts finder. Look in sound system parts. There you can find the part num of your model year radio and compare it to other years to check for compatibility.
I put a 2008 Harmon Kardon in my 2000 -- the only thing that was different is the way the AVC works (it doesn't adjust automatically with the 2000 pick up system) -- everything was plug and play
