Remove them adding the related DeviceConfig_Disabled.xml, for example :DeviceConfig_VideoPlayback_Disabled.xml and UpdateDeviceConfig.xml in Garmin folder. Safely Disconnect nuvi from pc and restart it.
What do you mean by "remove them"? Remove what? Do you mean edit "support_feature.html" (ex. delete Video Playback) then paste DeviceConfig_VideoPlayback_Disabled.xml and UpdateDeviceConfig.xml in Garmin folder.?
