Hmmm the page I linked to is specific to the non-hard drive systems and Sync didn't come on these models until 09. If you download the instruction manual the radio is the Pioneer unit which is what is in the 07-08 Expys and Navigators.

Maybe contact then again using the specific model number listed on their website. Not sure what Sync would have to do with it anyway as its only for Bluetooth and USB functionality.
