This is location dependent so if you have time to look deeper I am more than willing to give you a helping hand. As long as you know how to edit text file in terminal, you can debug this. The GuidancePanel component defines this header. The text comes from either routingModel or guidanceModel. You just need to dump the variables to figure out what happened. It could be a limitation in the API or could be blocked by the various conditions defined in the if..else block. Do you have a Symbian device for reference? If Symbian doesn't show next maneuver then you know for sure it's API limitation.
