I don't know about a external antenna, but I do know they had a slow processor in the earlier models that caused them to be slow to react and do some funny stuff when Navionics cards were used. They came out with some updates that supposedly helped that. Might want to check your unit and see what version it's running then check their web site to see if yours is the latest version.
