@Xinhuan: No, Zygor's Guide comes bundled with Cartographer R2290 (v2.3.6a) and there are problems with Cartographer_Waypoints as described in my previous post.
Zygor's Guide also supports TomTom but TomTom is even more unreliable than Cartographer_Waypoints.
The Zygor developers wrote the following yesterday:
The guide can handle TomTom, but TomTom has many known issues in it's programming that cause it to be less reliable than Cartographer which is why we don't guarantee full compatibility with it.
TomTom is far more reliable than Cartographer so I don't know wtf hes smoking. Cartographer2 is mostly dead right now and nobody should be expecting any fixes for it that are more complex than one or two lines.
