Firstly, I have removed your duplicate thread.
IQ routes is a map feature, not a navcore feature (as long as the navcore supports that particular IQ map).
The 9.465 navcore supports all maps (and the features that come with them). Therefore, you need to download a map which comes with IQ routes. The 4444 map is just a basic map with no features. For a list of features available with each map, see the compatibility chart:
As you'll see, the green ticks under the IQ/ALG column indicate that those maps support this feature. For eg. the maps 895.4438, 4448 & 4449 all come with IQ routes & ALG.
