@andrew Third for the Garmin Streetpilot.
No, I don’t agree. I have two Street Pilots, the first was the StreetPilot3 and when it came out it was as good as you get – better than Magellan etc.
I now use a Navman, it is faster to start up, faster to acquire the satellites, faster to recalculate if off course and runs far longer on its internal batteries. It also cost less. It uses exactly the same software (Licenced to Telstra) and is simply more convenient, light and pocketable but with the same sized screen as the Garmin.
