I tried it on the Expedition and couldn’t make it work even with the splash screens confirmed on my Sync update. Changing it in FORScan didn’t produce any results.
Well that is annoying! I never actually tried it on the Expedition, cause the wife didn't want it changed, but I saw the settings. Just assumed it would work. You rebooted the unit after the programming change? Not just turn the car off and back on, but held Eject and the Next Track button to do a reboot.
