thanks for this (bad) information. Looks like the Oregon 600 (an outdoor device) uses the newer algorithm.<br>
Well, it means, I can now stop optimizing for the "correct" route, and perhaps rather try to "optimize" the calculated time for the selected route (i.e. get it closer to my driving times)...<br>

Hi Bernhard,<br>
<br>
Garmin has 2 version of routing algorithm, older and newer. Older is used by Mapsource, older nuvi, probably by outdoor devices. Newer algorithm is used by BaseCamp and last 2-3 generations of nuvi.<br>
<br>
Newer algorithm is designed for speed of calculation rather than quality of results. Finding fastest way is based on road classes. At longer distances device uses only class 4 roads ignoring shortcuts with lower class. That's why you can optimize route manually.<br>
<br>
Older algorithm is more precise, it can use lower class roads, when class 4 roads are missing. Calculations are longer. But probably you still can find better route manually.<br>
