Never tried to get a connection for the gps thingy, however i could link my ipad to my iphone to use the phones dataconnection. Worked only once i switched on the personal hotspot thing on my iphone though, before that they couldn't see each other. First switched on the hotsport on my iphone, switched on bluetooth, then went to my ipad and the bluetooth settings, switched it on and once it saw the iphone i could pair them.
