My two Garmin units have never networked from day one. Figured it was a settings issue or user error. Finally hooked them up using an office cable and they networked immediately.
Not wanting to go through the time to take back to the dealer, I bought a new cable locally and want to try to replace the original. I need tips on doing this. I guess I will attach old to new? Is there a best direction to pull? How durable are these cables?
