How weird. I still can't believe no one has come up with a solution for this lack of functionality. I guess I have to keep searching! Is there any other way to do SMS via bluetooth (other than DUN and the SyncML method you spoke of)? Some of the SIM access profiles sound interesting. I should probably get in touch with Tomtom to figure out exactly which profile they're using. Thanks!
