I hate Garmins route choices, you have FAST routes or SHORT routes, short routes take you across single tracks at 15mph, fast routes add 20 miles on to your journey to keep you on main roads.
Short on the Garmin always takes me...
That takes around 30 minutes across winding country roads.
Fast always takes me....
That takes me around the same time but is around 15 miles more than I need to cover.
The TomTom and Navigon units take me down the main road and then cut across when it is quicker to do so, not at the first opportunity...
That route takes around 15-20 minutes.
Might not seem alot, but that is just the last 20 mins of the journey, if you have driven for 4-5 hours that sort of route choice can make a huge difference.
Annoyingly I updated my Navigon recently and it too has started acting like a Garmin, then when I enquired Garmin bought Navigon out, and now they are using Garmins routing!! And I can't roll the software back.
But when I got the new TT Go 600 everyone was saying it was crippled, no zooming out on the map to look at alternative route options, it would just zoom straight back in again. That alone was enough to make me return it.
In the end I got a nice Double Din Alpine unit, they all run copilot and iGo, which seems brilliant in comparison.
