Ok, so the screen info for the safety warning when first logging onto GPS is not part of the Data.zip:ui_pioneer folders. My current assumption is that this is something which could be seperate from the GPS application and maybe part of the mainmenu.exe.
the xmllegal is not it which is referred to in the ui_pioneer folder under file: legal.ui & legal_800_480.ui.
I will investigate the matter further.
Ok, The screen is not located in the Data.zip file. 100% certain.
When you remove the folder - APL2 and load up Mainmenu.exe. It will load the application. When you click on the Direction icon for the gps, the caution screen comes up and then is quickly switched over to the menu screen of the GPS automatically. (I DO NOT SUGEST YOU REMOVE THE APL2 FOLDER) This tells me that at least we might be able to some how get rid of the caution screen automatically in one of the files in the APL2 folder.
The GPS unit remembers that you been into the GPS section already and wont ask the question. It does not mean that the unit itself stores a value in a file that you did so, it could possibly be paging and referencing a memory/RAM location to store the value. This would make more sense for the unit to do so. This is the most likely event. If it actually is storing the value in a file (very unlikely) the unit would have to reset that value every single time the unit is started up and it would be located in its startup sequence where you might be able to set the value to a true statement instead of false.
