SP is supported Caty, i can run this map on both 2610 and 2720. Maybe with a step-by-step he will understand where he's gone wrong:

You are either misunderstanding or not listening to what caymag is telling you repeatedly. You haven't installed the map as a PC Version. By selecting the second option after the Licence Agreement screen you are simply remaking the GMAPSUPP.IMG and copying over the one already previously made and saved to C:\MyMaps\navigasi\Garmin as clearly shown in your first Screenshot above. Go back to the start, run navnet_Garmin_v252-NT.exe again and at the following screen check the other option 'Install maps for MapSource application':

BTW, so that you can see which map you're viewing and have a dropdown selection box to change easily, in BC select 'View'>'Toolbars' and then check 'Map Products'. Also, your existing map images on the SP can't be seen if they have an MS Flag of '1'. It must be changed to '0' for maps to be seen on the unit by BC. Any map generated by MI will have a flag of '1' as will the GMAPSUPP.IMG made directly from the navnet exe. So if you wish to see them using BC you must take the previously compiled GMAPSUPP.IMG [C:\MyMaps\navigasi\Garmin\GMAPSUPP.IMG], change the flag using GMAPTool or ImgTool and load it using SendMap20 as i explained earlier.
