New Oregon 450 & Topo 100K
« on: December 11, 2012, 04:22:21 pm »
New Oregon 450 user here, and I’m still in basic learning mode. On the advice of a friend I purchased US Topo 100K, and have the portions I frequent (SE US) loaded. The friend also has SE US Topo 24K.  The 24K will route, turn by turn from A to B, but over the same route, 100K will not, the error message is “Route calculation error: Maps do not have routable roads in this area”.

Does that suggest that I can’t route using Topo 100K, or does that suggest “operator error” which is my usual problem. I had planned to buy City Navigator, but have not done so yet.

Note we each have the maps loaded on to a micro SD card, and we have been swapping cards to compare features of the map sets, and the 450 Vs Etrex Vista hcx.

Your experience is correct with the current map releases:
  • Topo 100k does not provide route calculation. See product feature that it "Contains roads, trails and highways in metropolitan and rural areas" without mention of the key word "routable". Meanwhile, I had posted earlier instructions for use of free Open Street Maps.
  • Topo 24k does provide route calculation. See example Southeast route from Garmin. It "Contains routable roads, trails and highways in metropolitan and rural areas".
