As well as a basemap, further to what dasilvarsa's asked, have you added an unlocked NA detail map? To be recognised, the detail map must be either fully unlocked [if from another unit such as your 50] or have the correct unlock files for your device if the map was purchased for it. If you're using unlocked maps, make sure there are no other .gma & .unl files copied over from the other device. The POI's etc that you search for with 'Where To' are embedded in the detail map, not in the basemap. Did you add extras such as voice files only with WebUpdater? Some of your nuvi 50 files are perhaps incompatible with the 760, better to use only those from WU to be sure. If you aren't sure, post a screenshot or files list of what you have in the unit's .System folder for a start.
