Both my '04 and '07 GT's cruise controls function seemingly the same, and I wish they functioned differently, and I'm wondering if there's an "adjustment" to change how the + & - speed adjustment buttons function? As it is, I have to "hold" those buttons for "some period of time"... "seconds", before they respond and their response is seemingly not predictable. I prefer cruise control + & - buttons that will add or subtract one MPH with each momentary click.

BTW: I use my cruise control "a lot" as my typical driving conditions are conducive to cruise control usage.

Any suggestions?
