hi, > I have a TripNav TN-200 GPS which connects straight into the GPS port. > I get a location locked, set Waypoint 2, and I'm off and walking. Roman Schlegel ran into this problem just a couple of days ago. I wrote him to install another driver, but he did not tell me whether this was successful. And after reading your mail I doubt it. (You have a different GPS device) However I could not reproduce this behavior. What happens if you click on reset the GPS subsystem? Does this give you a lock again? > After a certain amount of time, the GPS subsystem stops working. > Kismac says to "See log file for more details." I'm not sure to which > one it's referring, but the console log says "IOConnectMapMemory > (ipc/send) invalid destination port (10000003)" This has nothing to do with the GPS subsystem. mick
