For the 7D, you *must* connect the GP-E2 via USB, hot shoe connectivity is only for the 5DIII and 1D X.

Canon states, "†When the EOS 7D is used with the GP-E2 the following restrictions will apply: a) geotagging function will not work for movies while recording; b) geotagging features will not work for movies when using the Map Utility; c) electronic compass information and automatic time setting is not available; d) transmission via the hot shoe is not possible."
