Weird and scary
After reading this I saw my TomTom suddenly lose location after doing the first part of the journey without issue.
Scary or what?
Fired up a spare Garmin which knew exactly where it is.
My (ancient) eTrex goes everywhere with me but doesn't get fired up. Just tried it and the copyright statement said 1999 to 2001 so April might be interesting.
I remember using this with Autoroute (2003 I think) and a serial/USB cable to navigate using a laptop. Happy days. When you didn't reboot with it still connected when Windows thought it was a serial mouse and much hilarity ensued (not).
