Not to make an already confusing thing more confusing but, Checking Ford parts on the HD radio option and opening up the parts illustration, it only states that Human interface 4 as the unit that would have the HD option and not all HI4 units have HD. Also in the illustration, the faceplate shown looks to be the 'Sony' face plate. Below are most of the parts related to Human interface 4 along with the parts illustration. So, it would appear that if one wanted to get HD, they would have to have the HI4 ACM and related parts but, in only
appears that way and it
does make things a bit more interesting. Note the different amplifiers available as well. All related to the HI4. However, I haven't made a comparison to what I have, the HI3 ACM so, the amps and other related parts may be the same parts and are only referenced to the HI4 in the illustration. Let me make it clear that needing the combination of all these parts are probably not necessary to get HD. Just an interesting,
related, list.
