I recently hacked my Maestro 3100. I followed David Goeken's instructions on hacking the GPS from here: http://goeken.homedns.org/Weather/Magellan3100/Magellan.htm The hack adds TCPMP and FileManCE. I recently also added the MioPocket system but it really lacks the speed. So I was thinking about adding 1 or 2 other navigation systems like iGO8 or Navigon which have maps for the whole world. I looked at the thread here: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=135779 The person here is asking how to installing a new nav app. But all the links are dead that are in the reply's are dead.
